How can I programmatically retrieve the version of OMIVV (OpenManage Integration for VMware vCenter)?

This is how I would do it manually
1.Login to https://
2.From the left menu select APPLIANCE MANAGEMENT
3.Version is displayed under APPLIANCE UPDATE

There is no url under the Appliance Management hyperlink. It is a javascript action.
I would rather not have to hack all the javascript and html to find the source of the information as this could easily change in a future release rendering this hack out of date.

There is no SNMP agent
You cannot SSH to OMI

I would like to write a script to gather this information on a regular basis as part of a state of my environment management report.
