The idea I have is to do all the networking async based on a declarative 
set of messages in and recording all messages out and then hand that set 
of messages off to a syncronous layer to make assertions, record into a 
database, etc.

Thanks.

Guess I was expecting more of a response. I suspect I'll just end up 
cross-posting to the various mailing lists, which I hope won't cause too 
much offence or kick off any flame wars.

I'm faced with a difficult choice that I suspect many in our community 
are, just trying to find out how to make the best decision :-)
