FWIW, though I love and grew up in Austin, it an extremely dysfunctional startup/VC community, so unless you just have to have the cool factor, find almost anyplace else to start your company - real estate will be lots cheaper, too, and you might even have a functioning city government. As I said, I love it here, but will be leaving before too much longer, as it's going all the wrong ways, esp. w.r.t. startup culture.
