Looks like we need a third party software as Revit does not allow to get element ID. I've tried with shared parameter but couldn't get it. Any other idea?
I think it's possible that Revit dbLink (subscription) may provide this information. as it is a database and I'm sure those are the keys.
If that's not viable you can download the free Trial of Ideate Explorer or Ideate BIMLink to access this info.
Here's the Ideate Explorer method: http://www.screencast.com/t/eNv0zYbfh
