if you want to act on your ideas, I'd be happy to help out.
here's some site you may want to check out regard Search and Rescue (SAR) technology:
here's a simulation game: http://wolfpack.twu.net/SearchAndRescue/

(I'm also hoping my desire isn't so far out there -- define out there as you will -- that I'm really submitting flamebait.)
