Compile the kernel on Win32
Wouldn't it be cool to take the kernel source, strip it down (remove all
'drivers'), replace the memory and task (ELF) system with calls to win32
API, add Windoze specific 'drivers' (for X as well) and compile the thing on
Now you can run all the debian stuff (without any recompilation or such).
The downside is that some low-level i/o stuff wouldn't be supported.
Another problem is that it may not be legal to do so (GPL).
