So an update to my previous post on audio: I found the patch in Banshee bugzilla that enables transcoding support. Applied it to 0.11.0 and rebuilt, and it works pretty nicely: I can drag files from my library to my phone, then synchronise the phone, and they're transcoded to MP3 and copied to the phone as they should be. Very nice! It'll be awesome when this is merged into a stable Banshee release. Now if only it could somehow write playlists as well, in the weird-ass .apl format Motorola chose to use for some reason...
