Message Routing Paradigms

I am aware of Erlang's messaging capabilities and yet there is still a
general need for higher level protocols like the one's I mentioned.

Even the CosEvent module demonstrates acceptance of the decoupled
publish/subscribe paradigm.

Do you or anyone else have any idea of messaging "middleware" developed
with Erlang for Erlang that addresses message routing like the CosEvent
module, but without the overhead of CORBA?

I'm not sure there is really a need for a paradigm - it is the basis of
To get 10k per second you are probably not wanting to do a lot of
processing on each message - but a simple round robin load balancer
based on differently tagged messages is probably no more than a single
gen_server with a little logic
I'm not familiar with these different mechanisms but my guess is that
they are only needed because they don't have Erlang :-)

To whomever knows,
Are there any good information sources regarding Erlang message routing
I am interested in decoupling publishers and subscribers, possible
space-based load-balancing (like Java Spaces or IBM T-spaces),
content-based subject routing, and it must handle on order of 10K
messages per second per 1GHz CPU.
