Well, on Windows you're in luck, because it's that way since R7; the 
emulator is contained in a dll, beam.dll, which is linked to erl.exe and 
werl.exe. It is feasible, but not easy, to link it to your own program. 
Check the source for werl.exe.

Speaking of a better interface, I've been thinking of that for a long time. 
Werl is not much better than the command-line interface, and not all of us 
think that shell mode in emacs is the ultimate IDE. When I've finished some 
stuff I will look into it.
