Also, is it feasible to jack up the data rates even
higher - say to
several megasamples per second?
Several megasamples per second x 3 bytes per sample = 3x several (10? 20?
100?) megabytes per second. Add overhead for wire encoding and figure 10x
that for bits per second, so 100 to 1000 megabits per second, depending on
your definition of "several." Without protocol overhead, that is just raw
audio payload. So at the higher end probably even 1Gb/s Ethernet would be
not quite adequate. 2.5Gb/s Ethernet never really happened commercially,
so that means you have to move up to 10Gb/s Ethernet. 10Gb/s Ethernet is
very processor intensive, maintaining real time response while running
10Gb/s will be very challenging.
In principle it should be possible to run at those rates but it won't be
anything close to simple to get it working reliably.
