You can use WST for this. It supports more than just HTTP+Soap.
The HTTP and SOAP protocols are quite slow. WST has a binary protocol
and straight TCP connection which is much faster.

I'm currently writing a module for fpweb which plays the middle tier
for an ExtJS web application. There is no reason why you could not use
that with a regular FPC client as well.
