Announcing Dallas New Tech; Monthly Event to Preview Exciting New Technologies

What's the story behind the $10 reg fee? I assumed that it would include dinner/drinks/something but I can't find anything confirming that. I would've guessed it was a free event given that there's already at least one corporate sponsor (or so it appears). Failing that, I would've thought it was maybe a "members only" thing like Texchange. Do the startups doing the demo also have to pay to demo?
