The SXSW website just put up a schedule of the 2006 showcasing artists. The first page is for Wednesday -- there are links for successive days -- and showcases are listed alphabetically by venue.

Very handy, but what makes it better are the cassette logos (how old school) next to most artist names. That means the artist page has an MP3. What this means is that the SXSW is a big MP3 library. Good for checking out bands before seeing the live show, and notable because there are a number of MP3s for artists on labels affiliated with the four majors (Laura Viers, on Nonesuch, for example). It's no secret that the majors tend to shy away from giving away their music for free, even for promotional purposes.
