Launch one of 3 projects as an actual startup, quit dayjob.

1) infrastructure/platform related to security 2) hardware device with social network features 3) consumer-focused webapp in data aggregation/presentation

I've spent the last couple months since getting back from Afghanistan working on all 3 at early stages, finding potential cofounders, clients, funding, etc., and am pretty much at the decision point. Should be going full-time with one of them in January (I need to hit a vesting cliff of 12-31-2009 before doing so, counting down the hours...)
