Bonjour would be a good way for the two (or more) Macs to discover each 
other (or more likely a single central "server" with which they would 
directly interact).

I'm not sure what you have in mind by "share a stack" - but if if you 
mean it literally, I think that can't be done. If what you mean is the 
same stack being run on each client to produce a shared environment and 
experience, then it can be done and is fairly simple.

Simple multi-user games should be straightforward (unless you need 
high-performance, real time as in first-person shooter games). Shared 
drawing may be more difficult; just basic functionality shouldn't be 
hard, but to make it feel comfortable and smooth could be, IMO, very 
difficult - so it depends on what you're trying for.

Although not tutorials, there are some samples

1. Basics.
On RevOnline, under user alextweedly there are two sets of samples.
TCP:   "TCP App1" and "TCP App 2" are a client + server using TCP
UDP: "UDP Echo server" and "UDP Echo client" are a similar pair using UDP

There was an earlier discussion on the list about TCP vs UDP, but 99% of 
the time, TCP is the way to go unless there are specialized needs.

2. Advanced samples
The Chat server and client (original by *//Björnke von Gierke//* , with 
clients by various people) provides an excellent example of a complete 
application.

And, as I've just discovered, this is one of the examples in the RunRev 
Video tutorials - see
http://support.runrev.com/tutorials/projects.php

(I have to admit, I don't know how you obtain the sample stacks 
discussed in this tutorial - maybe they're part of the current 
distribution.  I also don't know how to get the stacks directly from the 
developers, they don't seem to be on the page that I had bookmarked as 
Bjornke's site, but  perhaps Bjornke will chime in.)
