Playlist management/syncing

  Rhythmbox as well as most other music players/libraries has its own 
made-up playlist storage format . That means No portability , and no 
simple synchronization solutions .That's why I'm trying to use JuK right 
now - it's the only linux music player that keeps the playlists on the 
disk (but it's kind of unmaintained, so prospects there are limited).
  So I have a proposal and I'm willing to start coding for it , but I 
have to know the idea is accepted first . So far my impression is that 
GNOME devs have no interest in 'people' , at least on the mailing lists 
. So a side question is - where do development discussions actually 
happen ? With that thought in mind please take a position on the topic . 
Here's the idea :

Playlists would get picked up automatically from the music library 
(indexed as entries in the db) . On startup they get loaded in the 
playlists pane , and on modifications they get instantly saved . 
Automated playlists are not affected by that arrangement (they can 
remain in the xml they are in now).

Pros to the current situation:
+ easy synchronization between computers using any sync solution
+ persistence of playlists on full wipe/reinstall of rhythmbox

I can't think of any cons .
