KernelEx is pretty cool. Could a co-kernel be cooler?

Most have probably heard of Co-linux. A now defunct project that loaded Linux beside/inside Windows. It was never developed for Win9x. Only 2000+. Now there is Windows Subsystem for Linux.

Also, the Aros distro "Icaros" has something called "Hostbridge". It installs Aros to Win or Linux. You can also create Aros Icons for loading native OS applications. I guess you could use Icaros like a shell replacement. But you don't have to.

Then there is BoxedWine. It fakes a Linux kernel on Windows, so it can run Wine. You can run older incompatible applications/games on newer Windows.

Running modern DX and GL, inside Win98, isn't going to happen. But we don't get that with KernelEx, either. The larger issue is the slow, but eventual, fade out of 32bit development. Even if that was bridged, the performance hit would likely be pretty noticeable. Still, the idea does tickle the imagination.
