The member menu is a resource hog, at least in 7.0.3 and under that I have tested it with. Because of this I won't even enable the member menu on most sites. Maybe it is better in 7.0.4+. I haven't had as much time as I would like for 7.0.4 yet...been putting it off for all the 7.0.5 talk I have been waiting for.

So If this will allow chat / simple messenger without the member menu bar 2 thumbs up.

I will check it and test more in my spare time, but it sounds like a much better alternative see more to the standard member menu/simple mesenger.
