Hi, what about a small shell script (or two) which takes an ardour-session-dir, compresses all the audiofiles with flac (its lossless isn't it?) and then tars the dir. On the other side it untars the dir, decompresses all the flacs to waves and your session is ready to be loaded in ardour. Additionally the peak-files could be removed (they will be regenerated cause the wav-file is newer than the peak file). What SEX is missing is the ability to join two branches of music. Example: A starts the song with some tracks, B takes it and adds the bass in an own snapshot. But while B is doing this, A also adds tracks. After A loaded the snapshot from B, he can listen and think about both versions but the info when B's tracks and recordings start are not usable in A's snapshot. Only the pure files can be used but what if the bass-track of B is in fact several takes which don't clue on beats? BTW: I wouldn't use CVS for ardour-sessions. Every VCS (version control system) sucks when it comes to big files. And CVS is so oldschool...
