+1 from me on Chicago Boss.  It's worth spending some time with - and
I think it hits most of the items on your list (as it is built on
Erlang/OTP and "inherits" a lot of the application characteristics
that are important to you.  Chicago Boss has a very friendly user
community and mailing list (just like Erlang's).  :-)

Paul.

P.S.  I'm just starting to go through Zachary Kessin's recent book
(http://www.amazon.com/Building-Web-Applications-Erlang-Working/dp/1449309968/)
which may be worth a look also.  It's not an expensive purchase, and
touches on some of your issues.
