Yes.  :)  I've also been meaning to get a working brain...one that
hasn't been fried on scotch, cigarettes and miniskirts. :)

That would be the idea.  Adding the getStream method would probably be
best because others (turba, nag, mnemo) will eventually need it as well
(as they're integrated).

Thought so.  FTP will do for now, but the Kolab-preferred method for
publishing free/busy is WebDAV/S, so I'd probably also pitch in to add
that support to the library (need to read the WebDAV specs first).

Moment? New project? I looked for it and could't find it in the FTP
site...is it CVS-only?
