Re: doubletwist still sucksth
Again, just use Subsonic. Install the application on the machine with your music. Set a port forward on your router. Use the web version for free, or pony up $10 (or less) and donate to Subsonic to get access to the incredible Android app. I've been using it flawlessly over the last two weeks as I bike to work and have used it regularly for the last year in general use. It's fantastic. No syncing, all super responsive streaming. And you can cache as much as you want on your phone.
Doubletwist is the old school iTunes style school of thought. And it's half-baked at best.
