Suicide Vests with a Remote Signaller

[Superlagg]

There *might* be a roundabout way to accomplish this now with MechComp. Implant yourself with a med-implant, wire up some sort of thing to listen to PDA alerts and detect if your name is dead, output that to a signal thing, and have that signal thing transmit to your detpack. Easy peasy.

Your idea's better though, much more likely to result in these things actually being used.
