Personally I think at the end of the day for this capability, this feature is really going to need to be built into the software as a specific capability.

Maybe you could utilize and expand on the WebDAV-sync infrastructure:

So we could create a "Resource File" and save it to our sync location. This file would define a "pool" of available resources.

Then we could point multiple project files to that Resource File.

The sync process could then look at the linked resource file to allocate and distribute the resources appropriately.
