I like your term "standard-wise". Although there is nothing in the SOAP
"standard" that prevents this architecture, it is probably open for
discussion whether it is "wise."
As it happens, the client and server *don't* share the same process space -
they don't even share the same computer.
And it *does* work, I'm running the software on a couple of systems in my
office right now.
