Andrew, I'm cc'ing this to the soapbuilders list because I promised I'd work
in the open.

Since our first talks about interop last month, we've made a lot of progress
working with other developers. We've learned a lot about what others have
been doing and have changed our implementation accordingly.

Yesterday we released the Busy Developer's Guide [1], which represents the
subset of SOAP that we are supporting in Frontier and Radio UserLand, and we
believe it is an excellent base for interop for many other developers.

I am writing now to ask for Microsoft's support. This is the format we can
support now. I feel if Microsoft wants to interop with a large number of
independent implementations this is the best we have, and it will work well,
based on our experience with XML-RPC.

We plan to freeze the spec tomorrow at 9AM and to have a compatible
validator running at validator.soapware.org at the same time.

I hope you say yes, and then we can get busy validating apps, and get ready
for a big party to celebrate interop in SOAP-land.

Best wishes,

Dave Winer
