Multi-Session Operations for Project Reality

I would imagine this could wait until ArmA 3. But has anyone ever thought of creating a persistent world system for Project Reality? I'm not talking about the MSO addon, I'm merely talking about the idea of persistence in ArmA. I bet there would be a way to make it work in a PVP setting. Also I think this could help promote using the entire map for missions, while still allowing for focused gameplay (maybe only parts of the map are in play at a time, similar to an up-scaled AAS system)

I got this idea while reading about the Multi-Session Operations addon, hence the topic title, since I think the two ideas do share quite a few things.
