Well, then the US users will just have to download them from over here? :)

Well, just one more 120 gig ide drive would be enough to add to that raid5
set, I think. I'll take a look at it. Need to get that machine installed
and so on too.

Because it is hell to try and mirror the images at release time when the
master machine is overloaded with a gazillion end users trying to download
it. And since other mirrors can't get to the images to mirror, more end
users end up at the master site.
Having the root of the tree hidden from public access is a good thing when
it comes to mirroring structures.
The administrative overhead isn't that bad, I'd guess at 10-30 accounts
that change very seldom.
