It will definitely be on a list for Ardour somewhere. Right now my Ableton-related activities with Ardour relate to fairly deep support of their Push 2 surface rather than Link. It would certainly be nice to see Link support, but not sure what the priority will be. I have another entirely new branch that is developing Live-like "clip launch" facilities for Ardour, and it is likely that Link support would want to piggy back on some of the concepts being developed there (notably beat/bar synchronization).
