It's a little slow loading at the moment, but I think I can fix this by putting all of the class files into a Jar (which results in fewer http requests/transfers). Let me know what you think. It's not a great replacement for any of the major clients, but I think will eventually make a good alternative to the web interface for people who can't install a client on the machine they're using.
Oh, it's called "Pepys". If you're wondering why, this might explain it :)
