I see a lot being done with communication between 2 RCX units. I was
wondering if anybody had done anything with RCX communication with more than
just 2 RCX.

legOS allows this with a networking protocol.
leJOS allows this if you’re willing to work with Jini.
Both of these require replacing the firmware with either C or Java.
You can build your own networking protocol in any language, really. Conceptually
it’s easy. Each robot has to have a unique identifier (a code of some kind), and
if another robot wants to talk to a specific robot it broadcasts that code until
the correct robot responds. That’s what I’d do. The sender might have to drive
around or rotate to find the recipient, but that’s the basic idea. If you want
just general messages like “Get out of my way” or “Hey other robot, turn left”
and stuff like that, it’s also easy to implement.
Here are a couple pages I found:
