I can see some attractions of a streaming server as an option, but I can also see some issues, not the least of which is that many people deliberately do not have their music PC attached to the Internet.

The streaming would also need to be rock solid if a streaming-based BiaB were to not miss timing of notes or chords and we could easily be streaming multiple audio here .... five or six tracks is common, twenty or thirty not rare, and as RealTracks are time-stretched, pitch-shifted and glued together from audio chunks within the RealTrack file. I suspect each whole RealTrack files would need downloading and caching before use.

MIDI of course has little size in comparison anyway.
