Application (in case anyone cares): Move better-than-FM quality audio
across a leased audio circuit with delay under 10 seconds. No
Internet exposure. Obviously one box is required at each end, and
the encoding box works much harder than the decoding box. Software
to run will probably be Ices -> Icecast -> network -> mplayer. Will
be using USB audio interfaces, probably something like the M-Audio
Fast Track Pro. Because of the nature of the application, once it is
booted up the only disk activity is occasional logging when there is
a problem with the connection.
Any advice, web links, battle scars, or advice gladly accepted.
Not quite a match, but maybe worth investigating the hackability: the
$99 Roku box sold initially to stream Netflix but supposed to be
getting other capabilities. Or for just audio, their soundbridge
products that are more expensive but some include speakers.
Development specs are available for the soundbridge along with source
for gpl'd code included with the netflix box. Not sure about
development on the netflix box, though. Might be worth $99 just to
take it apart and see what's in there.
This would be more interesting for the playback end (no audio input
capability is visible) if this were a one-time project, but we will
probably have to supply more pairs in the future, so a more stable
platform is more interesting. Price is certainly right, but unlikely to
hold, as they are charging $200 for their SoundBridge.
The netflix box is new hardware - and there doesn't seem to be much
reason for promotional pricing. They claim that they will release an
SDK soon for anyone who wants to generate their own channel (but not
opensource the box itself). But as long as you can send some
standard-protocol stream, why worry about matching the hardware? A sip
speakerphone might even work as an endpoint.
Here's an interview with the roku CEO:

The chumby is probably more hackable, but it already plays network streams.
