You can see the VNC WIn98 desktop (running on a laptop), as appairs from XWindow. On the laptop also run a Windows VNC viewer, pointing to Debian VNC server. This is the window titled "root's X Desktop (www.sanvittore.it). Can you see the xterm apps running on Debian side?
Ok,ok: you can see also the "Outlook Express" and "Internet Explorer" icons. I'm, sorry: I buyed recently this laptop (paying also for Win98) and this surprising pieces of software are still unconfigured :)
Warning: on the laptop monitor there is a label "Designed for WIN98". Maybe, some specialized hardware, of course? I wish to be honest with you: I don't know if the same environment (VNC, etc.) will works on your general-purpose machine :))))
