This is a good idea; I've discussed this exact concept with a few different people over the past year. I'm glad someone finally executed on it.
I actually explored it pretty intently about 6 months ago and started to put a team together to pursue it, but decided against it due to lack of resources and time - apropos given my quote. I knew I'd have to shut down my consulting business and go full force at this one for it to have a chance at working, and the timing wasn't right.
You're on the right track. Let me know when you have another idea like this one :-)
anyway, back to jeff and his android work. i just found out that jeff's android scan has made it all the way to the 275K prize. congrats goes out to him. he slightly changed the name and the description; but CompareEverywhere still has similar ideas that i had. oh well, i suck and jeff rocks.
