devices in the same way we have a usb audio/midi standard.
It would be worth checking at the page for firewire support to see if
anyone has written a native firewire example. Takashi based the
usb-audio driver on the one for OSS which Alan Cox wrote.

I've successfully recorded 4 channels without dropouts between two
machines over nfs but not with jack. I can use jack without dropouts
just not at lowlat. I have to use 2048 if I want to use a few apps at
once. I usually use them on two channels. Recently I was seeing
problems with jack apps and lost the inputs for 3 and 4 so I have
updated to the new cvs. My last one was March 21.
It worked very well with jack until one of the last incarnations stuffed
up a whole lot of my apps. now jacklaunch doesn't work with terminatorX
again. I had it running a jackd session with ams, two alsaplayers and my
friend on bass for a night and I routinuely use it for sampling live at
concerts.
So far I have done some recordings with it but only in duplex because I
am still working on mixer techniques. I generally get audio lag while
using the alt out on the mixer into the device at 2048 so I haven't been
able to use it for serious four tracking.
I have done some interesting (to me) things with it so far and it's
fairly portable and rugged.
If you want something specific to recording the maudio delta series or
rme hammerfall series (maybe not hdsp9652) are very well tested.

========================================
Being on stage with the band in front of crowds shouting, "Get off! No!
We want normal music!", I think that was more like acting than anything
I've ever done.
