Who do you use for the 100mbps connection?
My friend John has a similar offer in Seattle too, at http://condointernet.net/.
(For those who are wondering, this is an extremely special case -- most home bandwidth in the bay area is in the <10Mbps range, asymmetric. The OP is using a service that's available at only a handful of SF apartment buildings.)
This sort of connectivity will never be feasible in the suburbs without massive government subsidies (something I had hoped our current administration would see the value in).
