In the meantime, following along on Dave's idea about running remotely
I now have Ardour running at 64/2. (sub 3mS) No xruns yet.

1) On Lightning I boot without X and start Jack in a console.

2) On my remote machine some audio apps are failing with lots of
'BadAtom messages, but if I log into Lightning using

ssh -Y lightning ardour

then ardour comes up remotely and seems to be working fine. I've run a
couple of sessions, and at least in playback no xruns yet. I'm also
playing oggs from a 1394 drive and have hdspmixer running. My issue
right now is this is a lot of network traffic and this room only has a
hub so I'm off to pick up a cheap switch at lunch.

I still see a lot of memory usage. That concerns me a bit.

You make some very good points below. I'll come back later today and
spend some time thinking and answering them. For now let me say that I
have <1% of the experience you do with FB solutions (I've NEVER used
it) so that's a whole new area for me to look at, but it could be
interesting.

More later, and thanks very much to you and Dave. I'm not done here.

Cheers,
Mark
