[LAD] Jack MTC/MMC slaving

   I'm guessing from the research I've done online and from the lack of
responses to my LAU message (
http://www.nabble.com/Slaving-jack-to-MMC-MTC-to20357929.html ) that JACK
does not currently support slaving to external (or internal?) devices via
MMC/MTC. I'm a C/C++ developer by trade, so I'm happy to get my hands dirty,
but I wanted to know what other work, if any, has been done on this front.
I've been told that both Rosegarden and Ardour can sync to MTC, but that
they cannot then drive JACK transport in that mode. Would it be difficult to
move this code over to JACK? Is there a reason this in't desirable?

There's a small program called jackctlmmc that seems to do want I want, but
it's a bit limited (seems pretty hardcoded) and I think that such a
desirable feature should be integrated into a more widely used program. Any
