The only issue i see is that all these rfcmp's or rfmods need to be accessed as individual downloads to make this effective.
I know ISI will use these ID's to identify what you need to join a server,
And i assume this information will be displayed to you when you click a server to indicate what you have or not.
So you would have a list of what you have or do not.
The items in this information have an embedded link to take them directly to the download,supplied when you submit your mod or comp.
The concept is simple but like i said these file need to be broken down a bit to allow only needed content
