Implementing Audio into a Linux based system that uses VNC

You could try routing your /dev/audio through a shoutcast server
(http://www.shoutcast.com/download/serve.phtml) and playing back on the VNC
clients with XMMS.  The sound will probably be great, but the VNC
multiplexed video will be less than satisfactory due to the nature of VNC
screen refresh for a standard 30fps video stream.  You will most likely
encounter lots of partial transition frames and some black-out frames since
there is no sync and all VNC knows is the video window has changed.

You will be lucky to see 1-2fps in tandem with streaming audio on a 100mb
connection IF you are not on an isolated network segment.  You should have
no other network services running including NFS, samba, router discovery,
printers, etc.   Even then I suspect video will be pretty bad.  But please
post back to the list and share your experience -- good or bad...
