Would be interesting, but to be honest, I kind of like keeping them separated and not because of the "one takes a coin, the other doesn't" argument." Like government, if a program tries to be all things to all, it tends to become bloated, unwieldy, and inefficient. MESS on its own merit, while there are a few people working on various areas, has so many systems in it the have been relatively ignored or imperfected for years.
