The state of SOAP.

What's the state of SOAP on rails?

This is what I can gather so far.

AWS doesn't work with rails 2.1.

There are two forks of it one from datanoise and one here
http://www.actionwebservice.info/

There is something from ws02 which seems pretty new and possibly
doesn't support WSDL.

I need to write some SOAP services. Which of the above is the most
baked and are there others I should be looking into.

Thanks.
