The network structure and our local API's are essentially synchronised:
its very hard to keep and maintain differences between them. A local api
that is very chatty between two branches requires a network api that is
very chatty between branches.

If we'd be happy having that in our local API, its not much different.
But it is potentially easier to modify the minilanguage.

I think there would be a steep curve before we started to benefit from
existing operations; like there has been with the network support at
all.
