Ok, forget about physical size for now.

Ok.

Ok.

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.
