Thanks to everyone who has already expressed interest! Definitely looking like it may be a go on the
project. I'll keep sursound informed as I do preliminary studies this summer.

not, I don't really mind), or a dedicated system that includes the
CPU, I'll want several :-)

Wow! Fantastic response .. lots to think about. Will let you know how I get on.
Part of the problem is hardware as I was unable (at the time I got this board)
to find a case with a HD Audio front panel so it currently thinks it's running
in AC97 mode, but I'm going to knock something up to get round this. In the
mean time I'm going to play with the suggestions people have made (Puppy is
currently booting).
I'm also interested in the paper that Fernando gave us a link to. Although I
don't want to use the Mamba hardware, I _am_ interested in the possibilities
for a dedicated multichannel player for installation work (another retirement
project!) What I'm looking at at present is a multichannel dac linked directly
(not via USB or owt like that) to an Arm processor that'll just play a
multichannel file off of a USB stick or SD card. For prototyping I'll be using
a BeagleBone (as I definitely don't want the extra bells and whistles of the
BeagleBoard itself) - I'd prefer to use the RPi but the chip used (at least,
according to the manual) appears to have a crippled McASP port that can only
handle stereo, whereas the ARM on the BeagleBone has a good enough
implementation of McASP that it can do 16 channels at 48k for definite (EAOE)
and probably up to 96k without too much trouble. If initial tests prove the
concept, I'll look KickStarter funding. The idea is to have an absolutely rock
solid box that just plays stuff without any of the hassles of systems relying
on computers (ha! That'll be the day)) The most it would have is an on/off
switch and play controls - but it would output up to 16 channels, balanced, 24
bits.

Indeed!
Let us know how the beagle board perform with a port of Planet CCRMA. ;-)
I will, I just have to find the time to test. I'm curious whether a small box
like that can drive 1/2 of the Mamba box I was driving from a regular desktop.
32 channel playback through an ethernet port[*]...
