Hi, Dave!

Here are some comments:

>We looked at WDDX and saw that it was a subset of XML-RPC.

Not really. WDDX is explicitly about not being related to RPC. It deals
specifically and only with data. There is no notion of request-response,
objects, methods, and interfaces.

As far as data is concerned, apart the fact that we expose a recordset
datatype, our datatypes are indeed similar.

This is done on purpose, since WDDX is only about describing data. Yes, HTTP
makes the most sense for moving data around the 'net. I recently saw an
example of a WDDX-enabled app that pulled data from an ASP and a ColdFusion
server to later display the data in MS Word. HTTP and DCOM were involved. I
also know of applications that use WDDX as a structured representation for
data they persist to databases.

Yes, this was an interesting article!

Absolutely. I'll contact you on a private channel.
