It would take _a lot_ of work because it so heavily uses libraw1394,
libavc1394, and libiec61883 which is a completely different set of
APIs than what is on OS X.

All you need, but not others. In my experience, if you make a partial
or limited feature, you suddenly receive requests and bug reports to
extend that to its fullest extent. As an example, you want to extend
the FOSS "feature" that is dvgrab to OS X ;-)

Alas, there is shared interest with the Kdenlive project, of which I
am a part, because Kdenlive is ported to OS X now - naturally, with
some problems to work out - and it would be nice to use its dvgrab
integration on OS X. However, again, I am very busy, and with limited
time. So, yes, this is on my ToDo list, but not near the top. It will
likely come eventually from me, but it would be great if you can
recruit someone else if you want it anytime in the next year.
