We're developing an HDA versioning system (that checks out to the users local directory and versions up, then you publish the hda back to the server once the changes have been made).

The problem is if you have multiple instances of that HDA in your scene and version one up, all the others remain at their current version.. and I can't figure out a good way to programatically update them all

One option (which I would like to avoid) is parsing the whole scene file for instances of that hda and updating them.. But even that doesn't work when one instance is local and others are on the server (or vice versa). In the asset bar it displays all the definitions for the hda but each definition can reference a different hda filepath. How are they being grouped together? In the asset manager those hda's are listed separately..
