While waiting for the hopeful Risk clone, I came across a neat work-around. I've been playing Domination, Yura's Java version of Risk (installed on XP box), a nice job with extra maps and card sets etc., which of course won't run on the N800 because it's a Java applet. But once I installed VNC server/client, I could play it remotely off the PC desktop. It's window on XP is almost EXACTLY the right size for the tablet screen. There is a Flash version that comes along with the install as well.
