It does. We've been dealing with some scaling issues on the Ubuntu One
servers, and so desktopcouch sync to Ubuntu One is currently disabled.
It'll be back on soon -- we're working on it :)

I'd also be happy to be involved in this, and being the dude who
designed desktopcouch I've got a certain amount of knowledge about this
:) I pinned down moch at UDS and talked about how you identify when a
playlist has changed; the best thing to do is to watch for the normal
added and removed signals on the treeview for each playlist, and on the
Playlist header itself (so you can know when new playlists appear or old
ones are deleted), I think. Since there are at least three people
thinking about or working on this, we should pool our resources :)

(Small bonus note: you can pair desktopcouches on your LAN without going
through Ubuntu One, which means that you can test this from machine to
machine even while our desktopcouch data sync is down. See the
desktopcouch-pair app in the desktopcouch-tools package.)
