Very much agree,
start simple and see how far we can push it.
Ok.
...
Almost everyone has fast
Ethernet, so lets stick with that for as long
as possible. It's easier to upgrade than downgrade! ...
Ok.

I then propose that this project (for the moment) consentrates on the
analog and ad/da part.
I.e.:
. design a 16bit 44.1/48kHz, line-in block
. design a 16bit 44.1/48kHz, line-out block
. design a 24bit 192kHz, line-in block
. design a 24bit 192kHz, line-out block
All with spi, without any consideration about multichannel, usb/
ethernet/whatever -- do the analog part good, then we can use it
together with "any" cpucard.
******
Would that be something which could move this project forward ?
In meantime while we are working on this, the thoughts about processor,
usb/adat/firewire/ethernet etc. may have its time to mature.
Those of you more interested about other parts of a future system can
work out thoose details so that they are clear when the analog/ad/da
blocks matures.

Ok, forget about physical size for now.

[about sizes]
At this stage, I'd just
say whatever is easiest to work with. Shrinkage
and prettifying can come later! The aim is to provide upto 8 audio i/o ports.
I
don't think we should set an upper limit, instead it would be
interesting to see how many channels the system could support. Initially line only, much easier to get a decent
performance. Also
there are *lots* of mic preamps out there and everyone thinks theirs is
the best :)
Ok.

Connectivity via Gigabit ethernet.
I don't
think the atmel can do gigabit. Fast ethernet (100Mpbs),
is a more realistic choise unless we switch cpu.
