I realized that it probably didn't work was because I don't have netatalk installed. 
So I started compiling it but I ran into more trouble... 
Update: Okay, I recompiled the client with debug enabled, and it's definitely picking up the appletalk packets.
So I guess it's just the fact the nobody else is connected to the server.
