I have a complete chroot'ed environment on my Gentoo 64-bit machine so that I can run all the win32codec and Flash stuff necessary to exist on the web these days. Much, much, much web content doesn't work with Linux 64-bit machines but works great in the 32-bit chroot. NOTE: This is not trivially easy to deal with all the time, but it does work when you need it to. I am also working to make my machine dual boot, 64-bit and 32-bite, so that I can evaulate different VMWare/Parallel's type solutions. Cheers, Mark
