The "official" position is, that the only such client is telnet, and telnet localhost 9000 in several windows lets you test the multi-user "features" (and bugs) quite well.
I'm not really fit with Java, in fact, I haven't programmed a single line in it, but I'm interested in that persistent connection feature - do you have any pointers where I could look for the right classes to use ? I imagine a remote control/remote panel for a mp3 player that also has status, progress etc. for multiple computers (wired home).
After talking to some Java wizard who told me that Java vs. Javascript interaction was not as easy as I thought, I'm thinking of actually writing a specialized client (in Perl), that embeds IE to render the HTML - maybe easier than doing it backwards by using IE to download non-http data ;).
