I'm sitting in the wireless (GSM/3G world) and waiting for the rest of you to catch up.
p2p distribution of data, with identification and authentication is done millions of times a day in 'my' world.
Of course, it's just a distributed smart card system that will be 'hardened' by inclusion of TCG sanctioned hardware.
But I have yet to get a message on my phone telling me I can refinance my mortgage at great low rates, or offering to add 3" to me...well, you know.
