This should be some geek ideas, is that true? Otherwise it's not so interesting

Well, about one geek idea I've already posted somewhere else, but I feel that this is the right place to repeat.
In our office we used to play Half-Life with colleagues. First idea was to launch it under Linux, cause we were sick of switching to Windows to play games. Well, we managed that. Now the geekness: My colleague launched Half-Life on linux machine (Slackware) with winex, exported display to other host. Host was Windows XP with XServer installed. And other colleague was playing Half-Life launched from linux on that windows machine.

Such a heterogenous system
EDIT: And the good idea for the nearest feature is to install Linux on Dell Axim Handheld, which ships with Windows mobile 2003.
