I'd rather see an integrated UAE, just to double click to play some good nice games, but an integrated UAE means AFAIK more than just easy gaming, the UAE (ie the emulator) should catch certain emulated OS calls and redirect to host OS functions, which would allow an app running under the emulated Amiga(OS) to communicate with AROS as if it was executing directly under AROS.
Sure this would make it considerably slower than a virtual 68K with a JIT compiler, but on the other hand the UAE solution gives you everyhing runnable under the Amiga and not just a few apps, float myCents = 0.000001;.
