I've tried weblobby, couldn't get the java plugin working... it seem like it was asking for permissions, I clicked "yes" but then gave up on me.
if anyone is wondering, i've loosely followed this installation guide:
http://zero-k.info/Forum/Thread/5954but I didn't compile my own binaries or whatever (u crazy?) just downloaded the compiled 64bit one in the comments of that forum thread... wasn't working at first, but somehow (not sure why) I got it to work.
