I've tried to run CoLinux before, but could never quite get it configured. But the urge to run Amarok while in Windows led me to this write up... and it works! It's still experimental, and I had to tweak the network adapter settings, but in theory it runs Linux programs faster than using VMWare on top of Windows on the same hardware. (But slower than just running Linux in the first place and tucking *Windows* away in a virtual layer instead, duh)
Another piece of the puzzle filled in in my casual quest to run Everything on Everything.
EDIT: It was originally developed for this open-platform PSP-like Linux handheld device. Now I want one of these, too.
