Hrm, I just looked those over (I had been familiar with oggz). It looks
like those both are thin wrappers around the stream protocol itself to
handle all the little nuisances, like filling pages etc. What I think I am
looking for is more of the multiplexer itself. When I didnt immediately find
a standard library that multiplexes over a single TCP connection, I assumed
it because with all the stream issues worked out in something like Ogg, it
would be trivial to implement. I gave it a shot earlier today, and there are
a whole number of issues that I didnt consider when writing a MUX, like QoS.
You would think you could just have a big loop in the heart of the mux that
select()s and does the read/write accordingly, but there are anumber of
issues introduced when you dynamically add a "channel", or if a channel
hangs, etc. So the multiplexer has to be a little beefier than I was first
assuming. Its still pretty surprising that a generic library to multiplex
over TCP is not more common. Something that would let you create a in
initial stream and then create "sub-streams" and expose a "mux_write()" and
"mux_read()" or something, and have the library transparently handle all the
mux/demux and messaging in between. If something like this *does* exist,
