I'm sure Capital Factory can host this. Also, get in touch with Josh Baer--he writes the Austin StartupDigest every Sunday, and it goes out Monday morning. It lists all the tech-related events in Austin and it's what many people in Austin read to find events. If you're not on it, definitely subscribe as well: http://austin.startupdigest.com/

If you need help with intros for event space, etc., let me know. Contact info in my profile.
