Your entire thread of comments here make me want to gouge my eyes out. A signed message on twitter? Low tech? What in the hell are you talking about?

I'm going to be the asshole here, because it is vitally important that no one responsible for security ever listen to what you're saying. You're advocating some Orwellian kill-switch mechanism based on unspecified "signed messages" over a third-party social messaging service (limited to 140 chars, no less), and throwing in meaningless phrases like "low tech". What about this problem leads you to believe we all need something low tech?

I am not qualified to design such a system. You are negatively qualified to even comment on such a system. Please stop.

I'll try to put this more politely:

Since you apparently neither understand what was discussed (an optional rather than an "Orwellian" kill-switch), nor the implementation options (a signed message via any broadcast mechanism), nor why using twitter as the transport would be feasible and "low-tech" versus most alternatives, you should perhaps refrain from commenting on this thread at all. - And especially not in that tone.
