SOAP - Are you using it?

I hear a lot of talk about SOAP, and the various WS-* specifications (e.g., WS-Security), but it is a rare occassion to talk to another developer who is using or has used SOAP (and, I don't mean the kind you buy @ the supermarket ).

Are you or the company/consulting firm you're working for using SOAP, or any other XML/web services technologies?

If so, what kind of projects are you using SOAP in? What problems has SOAP solved for your development project?

Looking forward to hearing some replies on this one.

We are beginning to use SOAP to access our Stellent content servers. Previously, I had written a function library using Stellent proprietary COM object to access it, but this has to run directly on the Stellent webserver.

I rewrote the library to use SOAP, allowing me to query the server remotely form other webservers. It is using MSSOAP.SoapReader30 and MSSOAP.DimeParser30.

The only problem I am having is accessing file attachments. I can request a file and write it to the servers disk drive using the .SaveToFile method, but I really want to stream it to the browser without writing to disk. I cannot locate a method that will ".SaveToString"

SOAP is going to make it easier to access information from a diverse set of webservers. It allows us much more flexability to let the Stellent server do what it does best, while letting our web applications access content.

I'm using SOAP for a few little things at work. The main draw for me right now is that we have a Web App tool that can use Web Services as data stores. Since we have a lot of data on different systems that this App can't access directly we're able to wrap them in Web Services so it can consume the information. Pretty handy .
