There is a program on the internet called "Radio" which allows you
to receive audio broadcast on any node from one source node using the network. 

It uses roughly about 1% of the network transmitting 8k blocks of data.
It was easy to modify the source to transmit larger blocks of data across the 
network (The source code is well documented). At near CD quality, 
the network saw about 5% bandwidth utilization.

It has been awhile since I have looked at the program, so I can't say
exactly what I did to change the block size, but I do remember it was
easy to do.

We used the program to play CDs through the network. The program does a good
job of buffering so that there was no noticeable sound loss (unless
there was heavy network usage).

I think I downloaded the program from:

vab02.larc.nasa.gov 128.155.23.47
