I think we are going to see an increase in the deployment of femtocells like T-Mobiles ... not just cell carriers (AT&T to follow T-Mobile? http://www.unstrung.com/document.asp?doc_id=129159&print=true) but by people trying to push content into living rooms:
Today's Femtocell Headline: Google invests $25 mil in Femto Cell company http://investing.reuters.co.uk/news/articleinvesting.aspx?type=breakingFunds News&storyID=2007-07-20T164556Z_01_N20392788_RTRIDST_0_GOOGLE-UBIQUISYS.XML "The idea is to plug Ubiquisys' so-called femtocell devices into a consumer's existing broadband Internet access equipment to create a short-range wireless link between the customer's mobile phone and the Internet to improve signal strength. The Ubiquisys devices will work with phones based on the latest generation of GSM, the most commonly used wireless technology standard, which is widespread in Europe and other parts of the world and used by two U.S. wireless providers."

I have Sprint network with Samsung phone unfortunately locked in for 2 years. However, the T-Mobile offering looks appealing. So you had session persistance? Nice. Can you re-clarify that you did not have to re-authenticate at all? For example let's say you walk out of Starbucks. Doese the cell phone seamlessly switch to the TMobile carrier network? Thanks.
