From what I remember at the time of the initial discussions:

No. Nor would a merger really be that conducive of a match I think. MeeGo is (right now) primarily focused around OS hackers, slowly moving on to application developers and enthusiasts. maemo.org has a large end-user segment that doesn't really have a place there, at least, as far as I can see.

It's going to live on in its current form for as long as it is useful. I imagine that it *will* lose critical mass at some point and die off, though, unless things drastically change pace (through new blood etc) or focus - and when that point hits, I imagine the lights will probably be turned off, as there's no need keeping them on with nobody home.

The purpose (I guess what would pass for a constitution) has been outlined already in this thread: http://wiki.maemo.org/Community_Council - though it could probably use some additions of some of the things that have come out of this thread.

I guess you need to ask specific questions to get specific answers, though.
