I live in Austin and SXSW will be here in 4 weeks. IPhone has 2 apps out for this. Will Droid have an app soon? This is a perfect venue to have a smart phone.
I don't know about an Android app, but here's a link to this year's torrent download:
2010 Torrents (Home of the (UNOFFICIAL) SXSW Torrents)
It's just over 1000 MP3's this year (about 5GB). I haven't tried that link yet, but I've had no problems in previous years. I'll have a chance to get mine going in a few days.
