Hints and tips on streaming audio to the N770, N800 and N810 Nokia Internet Tablets. Those are the models I own, these tips may well be useful for other models and even other devices.
For several months I did this using Helix DNA producer - the Open Source version of Real Networks streaming media system. It's very good and you can do all sorts of clever things with it, but really it's overkill for this particular need. The easiest way of streaming from Spotify (or iTunes) running on Windows to a Nokia tablet is by using DSBridge.
It's a long time since I last used Wine, but it seems it really does work quite well these days, and installing Wine, Spotify, and getting it running on Ubuntu is dead easy.
