Prior to adding the managed C++, it would be platform agnostic. With the
managed stuff in there, not a chance.

Simplest way is to sit on top of the engine and catch the calls in and
out (basically, provide an interface layer). As to getting that to work
I've not a clue.
Calling the other apps from C++ is simple enough. The only caveat is
knowing what platform you're using. If you're on a non-MS platform, find
is mono is there, if it is then just use system("mono cpp.exe). For
Win32, these should have the .NET framework already tacked on, so see if
it does, then system ("cpp.exe") otherwise find mono (as above) or else
I'm not sure how you'd go the other way.
