I have spoken with people at NASA about getting a copy of the World Wind imagery (e.g. Blue Marble, Landsat, aerial imagery, or whatever we want). If provided with additional disks of imagery data, can they be added -- probably to the production servers?
I think the internal space for disks is pretty much maxed out. We have a couple of arrays sitting in the toolserver rack which we might use for something like that. Flat file data may also be hosted on the big file store box we have in amsterdam.
So... it's possible, it's not trivial though. The people to talk to are mark and river, I suppose.
