I just tried it but the client always quit with an EOF-error. The bugtracker has this problem listed but unfortunately not solved.
Additionally, server based irc-clients take up much of the server performance.
I know it's not the perfect solution but I have made a costum package of bersirc for win32. It's very small and lightweight, doesn't need an installation and starting the bersirc.exe should instantly get you in the oa-channel.
I'm not sure about all linux distros, but AFAIK most of them have an integrated irc-client.

edit: I've added a fully automated exe that makes it even easier to start the chat (oachat.exe) on windows
