Alok Mohindra, one of the guys who had his laptop open, presented a proof-of-concept for FonoMe. The idea, crowdsourced at cambrianhouse, is to allow laptops to receive phone calls with Google Talk, via open source frameworks such as asterisk. Simon Law phoned the test phone number and after some fiddling, they could talk to each other. This would be really handy for business travellers who want to keep in touch with their clients. However, GTalk has a very limited subscriber base, compared to MSN Messenger for instance. But still, I am very interested in the "hack". By the way, with a account, he can receive 2 phone calls at the same time.
