[Estanislao Gonzalez]

Hi Bryan,

I don't think it is important to be available 24x7. I hope (probably is 
not developed, but will be pretty simple to do) that the Gateway caches 
the last registry document found, so that it can be still restarted 
without problem if precisely at that moment PCMDI's central registry is 
not available.

The worst case scenario would be if someone wants to install a Gateway 
anew and at precisely that moment the registry is down. this could be 
solved by packing a "pre-cached" version of the registry with it (not 
that I think this will be that important, as adding this new Gateway to 
the federation will take time).

So while the server is down, no new Gateway can be added to the 
federation, nor any other changes be done. But the federation itself 
should work without a hitch.

But perhaps I'm missing something here...

Thanks,
Estani
