Is anyone aware of a service for mapping RxNorm to other drug databases like First Databank or VA lists?

At least one of the commercial vendors for XDS registries offers this part of their solution, which is very attractive - but it would be more attractive to have an open source XDS supported by a  neutral vendor (at least in healthcare). But this would be one problem we would have to solve if we go open source.
