Using the Symantec DLP SOAP APIs from Python/PowerShell?

We're trying to add some much needed functionality to Symantec DLP via the Reporting and Updating APIs, but the examples are all for .NET and Java. Is anyone using the API with scripting languages like Python or PowerShell? It looks like a standard SOAP interface, but I'm not getting very far just by poking around. 

I'm also not getting very far with the compiled samples. When I try to use the Reporting API executable, I'm getting a 'SecurityNegotiationException: Could not establish secure channel for SSL/TLS" error in response. We've got an external certificate on the server that's working fine via the WebUI.

Anyone have anything helpful?  :-)
