The idea is that most things like DB access and API items are changed before the scheduler/rpc layer and the items below that should maintain compatibility. In other words the RPC versioning is intended to allow you to do exactly what you describe here. Honestly I think the best answer unless somebody else has tried it is going to be "If you have the patience and don't mind it possibly not working; give it a shot". It "should" work, but I don't know of anybody testing it. I'd love to hear how it worked out if you try it. John
