Part of why I stopped responding on this thread is hesitation on this particular topic. There has been a certain amount of bad blood over the topic within the devteam and community at large.
I still PERSONALLY believe that a merge is to the benefit of both sides of the project, but I'm not going to harp on that point any more than I have on this thread already.
That said? I think "Multiple Archaic Machine Emulator" works extremely well, and I would personally vote for that name if such a merge were to happen at some point.
