As JJ mentioned earlier, there are DosBox ports for Amiga-related PPC systems so test yourself or ask someone to do so :p (although it has no JIT afaik).
DOSBox works nicely on my microAmigaOne. I was able to run Apple II emulator under DOSBox. Video:

Running DOSBox on Amiga68K is pointless. Better use PC-Task or PCx, both of them will run magnitudes faster on 680x0 processors, because they are written for these machines in first place, without portability intentions. I remember PCx was quite useful on my Amiga 4000/40/25 MHz. I used PC emulator for a utility to convert .MOD files to Sega Master System musics.
