Thanks John,
The mouse problem is caused by the kernel missing usbmouse, as I didn't
have one to test it when I built the kernel (got one now so the next
build should be ok).
It's great news that it's working with Nvidia cards, this is a mixture
of X.org's X11R6.7.0 and Jennifer Dillon's modeline XF86Config.
Testing reports are always welcomed as getting feedback on how things
work on different hardware configs is the best way to shake the bugs
out.
Regards
Phil

The current top Ethernet standard specifies max

You can also run Ethernet over Firewire. IIRC the max. number of
devices on a 1394 chain is 63 making Ethernet more suitable for large
clusters of interconnected MIDI workstations.
But to an extent arguing over which PHY layer is like a Vi / Emacs
flamewar.

For a working example of a MIDI over Ethernet (and UDP) have a look at
IEEE P1639 (was called DMIDI):

This acts as a bridge between ALSA and the network so all MIDI apps
can
bounce MIDI data between remote machines without any code changes.
I'm also working on an embedded Linux for clustering audio
workstations,
Live CD available (USB mouse support broken just for now, PS/2 OK):

This is also a call for participation in the final development of the
standard as well as application development.
I gave m-dist a whirl this afternoon and you my friend, are on the
right
track. I may be able to help with testing.
For some reason, my USB mouse wasn't autodetected (passing the
autoprobe
option seemed to help) but it locked up once I got a desktop.
I was impressed that it booted into X because I have an Nvidia card
and thats
always a hassle.

But if youre going to do that, why use ethernet? You'd need dedicated
NICs
and switches, so you may as well use firewire, which has dedicated
realtime channels, more bandwidth and doesnt require switching. 400meg
Firewire cards are down to about 7 or 8 euros in the UK now.
The only disadvantage is that you can't (right now) cheaply run
firewire
over long distances, but taht will change once firewire over CAT5
cards
come down in price, and this is rarely an issue with clusters anyway.
