Everybody is wanting AmigaOS on x86, but lets see other way around that would stop people complain - Windows NT sandbox in AmigaOS.
Note: I am not a developer, just think it over.
Yes, its huge effort, copyright problematic, but then again, Windows NT kernel (e.g. Win NT 4, Win 2000, Win95) would be enough to run most of Win32 apps and would satisfy the basic problem of Amiga - lack of heavyweight applications.
Some cornerstone there is:
Windows NT4 PowerPC - maybe some kind of mixed solution where kernel is already PPC as well as drivers,
could be used to run just application calls in emulated sandbox, similar way as AmigaOS 4 is limited compared to Amiga OS 3
Would need NT 4.0 drivers for SAM boards and X1000,
as well as some application wrapper, x86 CPU emulator
