yup - esad handles this.

one example:

mpg123 -s file.mp3 | esdcat -s other.machine.name

the "other.machine.name" needs to be runing esd and you need permission
to esd on that machine. this means the contents of ~/.esd_auth must be
the same (ie just like ~/.Xauthroity) - this is the auth key (the user
who ran esd gets an auth key and only those wiht the auth key
canconnect to esd) you can do the equivalent of xhost + and - wiht
esdctl unlock and lock.

but yes - its perfectly possible :)

->  
->  Is this very hard to do?

nup. see above.

->  Would this eat up too much bandwidth? 

44.1Khz 16bit stereo will need about 170Kb/sec.

->  Would this cause security issues?

not if you share the auth key and not flagratly use "esdctl unlock"

->  I can find cool apliances for this like doing a small chat app that would
->  just connect to the listener's esd to play the sound. 

alrady did this before in scripts :) works :)

->  Possibly we'd have to have a /etc/esd.access to state who can connect to
->  esd.

->  Am I still stable or is this I just wrote a major mind core dump? hehe
