It's not fair to blame the small Austin startup community on UT. Austin doesn't have angel investors and VCs tripping over themselves looking to fund the next Twitter killer in the same way that the bay area does. It makes for a smaller startup community, but also one that is more focused on building real products.
Full disclosure: I graduated from UTEE and have worked at some really great small companies in Austin.
Just the other day I was pleasantly surprised to notice my MacBook using IPv6 to stream a song over to my Apple TV (remote speakers). For grins I disabled v6 on the interface to see what would happen. The stream cut out briefly and then resumed over IPv4.
