It's so simple...
Target AROS to a VM (UAE) that can be hosted under any OS, so everyone can benfit from it. For a 'native' solution simply host under a minimal Linux distro.
No more need for Amiga Inc.and thier 'IP'.
No more Driver headaches.
No more faffing about trying to reinvent the wheel.
Ridiculously high compatibility with the existing software library.
For that extra kick simply have x86 binaries a la Amithlon (which is apparently possible in UAE) for CPU critical tasks.
