Me too!

I would also like to add that using email as a transport for business
documents to a web service makes a lot of sense - especially as:
1. The majority of the businesses in the world can't afford the
communications or adminstrative cost of an "always on" HTTP server.
2. Business interactions are often, by their very nature, one message at a
time with delays of several minutes if not hours or longer, between the
sending of a message and the generation of its response (I nearly said

I suppose I'm suggesting that *one* of the valid use cases for a web service
is one where at least part of the service is performed by a human being.

Do these ideas fit into our architecture.
