ActiveResource and SOAP

Hi guys, I've recently been digging into ActiveResource and the REST
principle in edge rails.
I want to push things even further, since about everyone in the world
is doing SOAP (Yahoo, Google, Flickr) and more important, .NET and the
upcoming release of Microsoft Navision/Dynamics, I'm trying to enhance
ActiveResource in a way that it would make me possible to for example,
do a Customer.find(:all), which does a SOAP request to a .NET
webservice, returning me all customers straight from a MS Dynamics
database.

I haven't written any code yet, but I was wondering if there is anyone
already busy with such a project or willing to help me get something
from the ground.

Best regards,

Matthijs Langenberg
