I would say the most "diffucult" thing about it ( excluding the security ) 
was designing the GUI for it. I used the standard AWT classes to accomplish 
that. And besides that you have to:
* Create a server ( seprate proggie ) bound to an unused port that listens 
for client requests ( I also impelmented a thread that checked before hand 
the desired port was availble ). I accomplished this by SeverSocket 
sever.accept(args). Then if a client connects, create a IOstream to read 
data in. Once you get data, you have to echo it to the other clients via a 
mulitcast socket. I should point out that I had the server runnig from my 
computer. I accomplised the sending of message by delegating an event 
handler to the "send" button which sent the specified string(s) to the 
server, which was in turn was echoed onto everyone connected to the server. 
Just start looking over the networking classes ( Socket, ServerSocket, 
InetAddress etc ) and check out Suns tutorials and it should be a piece of 
cake.
