I had a look at this, it all looks very straightforward apart from get where we need to either do a dance to set up a supply mapping or restructure to expose the core get operation internally without map lookups (the latter I think) and that doesn't seem terribly invasive. I may actually try coding it up next time I'm sitting in front of an appropriate test system.
