Does anyone know anything about multi-rope rappelling(more than 2 ropes)...how EXACTLY it is done, if anyone has done it, or if it can be done at all

secondly...could you simul-rappel off of more than 2 ropes? If so, how would that work?

Not sure what you mean but…
When you need the nearly the full 60m to rap down a climb you can tie two ropes together using triple fisherman’s knots. Using two ropes that are different in color is good since you really have to remember which side the knot is on so you can pull the rope through once you are done. Make sense?

You tie them together. put the knot on one side of the anchor, and rap down...then pull the rope.
Or are you asking how to cross a knot on rappel? You dont want to do this...crossing a knot is a bitch! I tried it once and it sucks. You only cross a knot on fixed lines, you can not cross a knot on a rope that you are going to pull...I dont know what you mean by "more then two rope" rappeling...because you can't rap on more then two ropes without crossing a knot

Ok, lets say you have a 60m rope, there are 3 pitchs and each pitch is 25m...
You get to the top and now it's time to rap, eh?
You tie the rope together (I use a figure 8 with double fishermens knots) and have the knot on one side of the anchor...remember what side the knot is on! Also remember to tie a BFK in each end of the rope so you dont rap off the end!
Rap on down to the top of pitch 2, or the belay of pitch 3...You can not reach the bottem!
Secure yourself into the anchor you just reached, and clip your rap rope into the anchor so you dont drop it. Now remember what side the knot was on? Pull that.
Set up the rope the same way as in step on and finish your rap to the ground.

So like, you want to cross a knot on a rappel, eh?
I think you better Ask Dr. Pee'd on about that.

Let me re-phrase the question...I will be rappelling off an object that does not have any anchors (except at the top), and i will need more than two ropes, meaning i will have to cross a knot during my rappel. How is this done? (and i will not need to pull my rope, so im not worried about the knots after i get down)

Passing a knot on rappel is much easier if there is something to build an anchor with (even temporarily) on the wall.
A classic example of this is the Lost Arrow rappell if you are doing the tip from the valley rim. You rap down and when you get to the station 1/2 way down you clip into it, tie yourself a backup knot about 3' below the knot then pass the knot around your rappell device.
However, you can pass a knot on rappell without too many problems. Bring your prussiks or your jumars though. Standard way to do it would be rap down until you're a few feet above the knot. Tie a backup a few feet below the knot and clip it to your harness (so that if all goes wrong you'll take a 5' fall onto your backup knot instead of dieing!). Carefully rap down to within maybe 6" of the knot, but not too close!. Attach a prussik or jug above your rappel device and slide it up so you are weighting it, not your rappel device. Then detach and reattach your rap device below the knot. Now you have to unweight the prussik (yikes!). Easiest way to do this is to down jug or down prussik with two devices until your rap device is weighted again. Then untie your backup knot and continue the rappel.
Hope that was clear enough. It's not terribly hard to do but it's not a beginner's rope trick if you know what I mean, so if you don't know how to use prussiks or jugs you're probably in over your head passing a knot on rappel.

If you are going to use prusiks, use a bachman with an unweighed prusik backup. Bachmans are easier to undo.

I have heard that you can sometimes rappell through knots with a rescue 8.
I may be wrong, I've never tried it.
My guess would be that your rope yould need to be rather thin and your knot pretty compact.
Good luck!

I once did something very similar to what you're asking. Me and my friend parangole had a 50 meters overhanging rappel to make, we had two ropes but, one of them was 60m and the other was 40. As a result we had to cross a knot if we wanted to reach the ground.
This is what we did: We decided to do a simul-rappel, and as we got to the knot (on my friends side of the rope) I used two prussik knots to anchor myself as he did the same but with Tiblocs, one above and another right past the knot. He then detached the rappel device and reattached it below the knot, released the upper Tibloc, weighted on the rappel device and released the lower Tibloc, after that, I weighted my device also, released the prussik knots and we continued our way down, no problem.
Hope it helped

It sounds like you have a specific place in mind for all these new rope tricks. Just out of curiosity what are you planning on doing anyway???

PBJOSH has got it right...just recommend that you try it close to the ground (like, less than 5 feet) a few times until you are comfortable, and under some supervision if possible. It's easy to get into trouble doing this - and fast...If possible, I also rig an accesory tie to my rappel tool to prevent dropping it.
Somebody was asking about simul-rappeling. If possible, I've found a lot of comfort in the following. After both people weight their respective sides, let one descend to the ground, then stay on rappel, locked off, weighting the rope while the other rappels. Requires some comunication, but it just feels safer having one person move at a time. Does anyone have any reasons for this NOT being a good idea?

Beyond_Gravity has already provided the link,
CHECK OUT DR P'S POST!!!
It is unfortunate that this thread has become as long as it has without anyone mentioning the Better Way to join the ropes together (thus avoiding the need for an intermediate anchor).
Read the link provided by B_G, it has all the answers you need.
Cheers
Fishy.
