Since it doesn't look like Genode is going to be ready to be a daily driver for a while, Qubes looks like something ALMOST capabilities based that I could live with. Some day I'll just be able to run stuff without worry.... but it's not going to be any time soon. Can I run old versions of stuff like MS-DOS or Windows 3.1 under it? Or my beloved Windows 2000? Windows 2000 with Office 2000 pro (with the patches to read the new office 2007 formats) would be awesome. I miss outliner mode in Word 2000.
