My personal opinion: if you can REALLY do what you claim then you should get every country's equivalent of the CDC working with you to MANDATE that this be part of every phone, and then of course you get the revenue from IP licensing.

In fact, I would broaden the scope a bit: make it like the "Emergency Broadcast System" for phones, only two-way.

Lots of privacy implications and the carriers and handset manufacturers would hate it, but I can certainly see it doing long term good.
