Ideas on display at Microsoft's TechFest

Microsoft researcher Mike Sinclair wants to teach two cell phones to dance. By holding two phones together and briefly moving them in synchronicity, Sinclair said that the phones can generate an encryption key that will allow them to share data in a way that even a determined snoop nearby would not be able to intercept.
There are millions of cell phones out there with Bluetooth wireless technology, ideally allowing for all kinds of ad-hoc connections. However, security concerns, as well as the difficulty of creating sharing "profiles," mean that few of these hookups ever take place.
