Current MorphOS system has lots of drawbacks/issues:
- Small amount of decent programs
- Limited memory addressing
- No protected execution
- Limited processing power on available HWs
- Outdated libraries
- Lots of time, effort to make the opensource programs to port/maintain (because of endianness problems, incompatible libraries, etc.)
- The ported tools are outdated
- Old Apple computers aren't a good option anymore
- No new HW for MOS available (on reasonable price)

And now, comes the idea to execute MOS on Linux in a virtualized environment? Hm...

Why not shortcut things: Execute those opensource programs (the ported and not yet ported ones) on Linux and all the mentioned problems are solved. And the resources are saved for the applications, instead of unreasonable emulation.

Why not try to make a Linux system to look and behave like a MorphOS? An Ambient like desktop would be a really good thing to see on Linux.
Maybe integrate UAE into the file handler to be able to start old Amiga games, demos, etc. A file handler with .ico files (others are hidden) would be really-really nice to have feature with all the cool programs, which are available on Linux (and no chance to port them).

I think a solution like this could be much more future-proof, since this is 'just' a new shell, a new environment. The MorphOS look and feel can live further without the huge work of porting MOS to a new HW platform. Such system will be no longer just a hobby OS... This can be used even for professional tasks, even for working, with a better user experience.
