[PlanetCCRMA] recording and latency with ardour

[Jason Russler]

With that hardware, you shouldn't have to many problems on the software side
maintaining a very small buffer for JACK, so software latency should be
minimal.  That said, I'd check with the Ardour list since there are a lot of
users there that may already be doing something similar (a lot of them are
on this list too I imagine - I am).
