while they settle down.  Or are we not dealing with UCD+s yet?

That would be sensible... however since we're practicing deploying 
AstroGrid components, one of the issues is 'what is the provider going 
to have to do and how can we make it straightforward', so I want to have 
the mechanism there as much as possible.

Let's do this - yes please.
