Any adult-biz oriented conference at SXSW?
 

or is this topic banned at the event?

XBIZ had a session there last year, but not this year.

interesting, what was the topic about? u remember?

Yes, "Selling Free: The Porn Industry?s New Economy"

I've done a few panels there, including one where I spoke on applying the adult affiliate model to publishing and related fields in general.
