Ooooh... so after passing credentials via commandline to the tightvnc.jar. Not only does JavaSE work, but it works fantastically. I had previously been using a HTML5 websockets proxy to get VNC client functionality with non-RDP/windows systems on the N9 (which obviously couldn't use java acceleration), and it was just horrible

In contrast, using tightvnc's java client is fantastically fast/responsive, ignoring the issue of no native virtual keybard support (perhaps someone here can turn me on to a solution).

Screenshot shows MS-paint (containing another screenshot), and the lil' menubar from TightVNC.
