Mark:

If your using a Browser, I've gotten it to work with XMLHTTP control and RDS.

If your using a VFP or VB front end, try a little experimenting with RDS. I once tried using it to test calling methods on a COM object from a VFP client and it worked. RDS is also geared towards using ADO record sets, but it seems to work with XML strings too. What you want to do is build up an XML string on your client that has the method your calling as an element and parms in another element. When your server receives the XML string, it parses it out to find which method to call and parms to pass.

The above methods refer to using HTTP and a Web Server.

If your connecting to a server via DCOM on a WAN, then you may be able to pass the XML directly as a parm to the COM server. Don't know, never tried it.

BTW, also keep an eye on the new SOAP\ROPE. It is designed specifically for this stuff.
