The Gentoo LiveCD with UT2003 had a really neat feature where you could load the entire UT2003 demo into ram if you had enough (min was 256 i think). I've been trying to emulate this with K, for example, loading and running Tuxracer from ram but haven't found an adequate solution. Basically, I've just been guessing (incorrectly) in the absence of a howto.
So how would one accomplish this? How can I give an option to load an app to the ramdisk and then run from there?

On a slightly different topic, how would I load OpenOffice.org in the background when the window manager (whichever, kde, fluxbox, etc) loads? We all know that that's what MS does to make MSOffice seem so quick, and I'd like to play around with it in K, but don't know how.

Any help, as always is sublimely appreciated.
