Good question :-) They don't, well not much, here's a support doc  
regarding iChat and Bonjour:


Here's the cherry pickings:

"You can use Bonjour to chat with other iChat users on your local  
network without using an instant message account or server. Each  
computer communicates directly with its neighbors.  Other iChat users  
who are on the same network segment (”subnet”) as you appear in the  
window. If you connect to the Internet using PPP (or PPPoE), you won’t  
see other Bonjour users. If you connect via a shared network segment,  
which is common with cable modems, you may see other iChat users. If  
your computer is protected by a firewall, you might be unable to  
receive messages from other Bonjour users. To use Bonjour, you need to  
change your firewall settings to allow activity on port 5298."
