Reading Extension data from MXD

Is there a way to read extension data stored in the MXD in Python?

We have a third party extension to ArcGIS. This extension stores information in the MXD according to Esri guidelines using the stream.write/stream.read capabilities of the VariantStream object.

We are trying to make our extension's capabilities accessible through a python session. However, there doesn't seem to be a way to get to any third-party extension data persisted in the mxd, or at least it isn't obvious to me.

Is anybody aware of a way to do this?

Thanks

I don't want to rain on your parade, but I also had 3rd party software (MapLogic) which I had to process with a .NET Add-In as the mxd objects created by MapLogic were not accessible to the python. The MapLogic representative tried to work with python, but was unable.

Do you work for MapLogic or is this just your alias?

Hi Micheal,

This is Babak. We've communicated about this issue a number of times. I thought I'd put a post out here in the forums in case someone has figured out something that I haven't been able to.
