Alright
so I am drilling and modifying set of Kong QD adding two steel cables to disconnecting levers with one master loop. click two draws to two anchor hanger, rap 60 meter, pull the 3 mm cord and the whole thing drops down to next ledge.
No , I am not goonnnaaa die cause under load, you can't push the levers inward to disconnect the draw.
just follow the green arrow and tell me what do you think?

I think that the weight of the rope may prevent you from opening the draw either. I'd do a couple test runs with the rope coiled up just to make sure it'd work. The other concern I have is that a full 60m drop (or more) could damage the mechanism of the frog to the point that this would be a one-time-use sort of thing.

Possibly. Maybe I should have said beginners and people obsessed with accidents shouldn't attempt to innovate gear use.

Kong Frog- $23
Bail biner- $2
How often do you plan on bailing exactly?

Seems more complex & expensive than the Texas rope trick using a retrieval line.
In addition to the worry about rope weight preventing it from opening, what about pull line weight causing premature opening?
Interesting, though.

yeah not to sure having a 3mm cord dangling below you that is ment to open your only safty, could get snagged, rapped around or PULLED by or on somthing causeing a premature release and then bye bye birdy makes me think its headed the exact opposite dirrection of redundancy, idunno seems kinda suicidal

Shades of the Decrocher Allain, another failed solution (considerably more ingenious) from BITD.
Are rescues slowing down? You trying to drum up business?
For openers:
1. You'll be dropping something on your head.
2. Once its fallen 120 m and smashed into the rock, it may not work. You may not discover this until the next rappel.
3. After release, if it drapes around anything on the way down, a flake, a tree growing out of the rock face, you won't be able to pull it off.
4. Once it is hanging 60m below you, it could wedge when you try to pull your rope back up.
5. After each rappel, it takes you half an hour to untangle the 3mm pull cord.
6. The nightmare scenario: you pull on the 3mm cord and the Frog doesn't release (friction of cord against the rock its elasticity make this quite possible, in my opinion). You don't know whether the attachment is still secure, or whether there has been some sort of partial detachment, so you don't dare prussik back up. At this point, you'd normally have to call for Majid---but you are Majid.
Have a safe climb.

MS, if someone else posted this, you would say some quick vague one-liner like:
'You will see when you die why this fails.'
Something like that.

Alright
this could be a solution for slackliners where they have two hangers on the other side of the canyon rigged to their complex unsafe highline and once they pull the trigger, the entire anchor comes off . no needs to go back to the other side of the canyon to DC the system but you better have the MS-kong in pairs when setting up the anchor.

Ah, but a highline across a canyon will be under quite a bit of tension - even when slacked off. So you're back to the problem of needing to release it while loaded.

slackline over a small 3mil cord hanging somewhere around my feet or below me? No thanks. I fall and the 3mil line cuts me pretty good. You could tape it up with the safety, thereby absolutely killing any chance of releasing it, but keeping it out of your way.
Remotely releasable highlines. What was that you said about complex and unsafe?

Thanks! Went chasing after that earlier today, but work happened. 
Couldn't find the right search terms.
There's also the stick one http://www.youtube.com/...&feature=related, not sure it's as reliably releasable. 
However, this looks interesting.
