No, unfortunately I cannot get access to the inner workings of the platform I'm using, but I have put in a request for enhancement for our devs to add a vSphere API plugin.
Is it possible to use those tools you referenced (PyVmomi or VIPerl) to generate SOAP calls? It would be worth it to me even if I have to setup the SDK or some other tools just to generate the calls I need for testing/experimentation purposes.
EDIT: I might have lied, we may have a Python adapter available. I will update soon.
