- Well, i think it would only be reasonable to run LINUX or NetBSD as a
- AmigaOS task, or a set of tasks.

- Since linux and netbsd is available at source-code-level, a replacement for
- their hardware drivers wouldn't be too impossible, f.ex. using scsi.device
- and a intuition screen instead of disk/gfx hardware. The hard part, which i
- know about nothing about, is how it's possible to set up the MMU in a way
- that it will work with both os'es running simultaneously,

- To have virtual memory support for every single program, you not only have
- to emulate the amiga, but you also have to emulate the whole supervisor
- mode of the CPU :(
