I found this neat little app that lets you Play online multiplayer against other people. Sadly as of right now the server is down but it should be up within a day or 2. Currently there are 2 games that you can play But there will be more because the program will automaticly update it's self. Also at 62KB its not a waste of memory on your PPC.
Below is the setup file.
