I'm 100% in agreement that the catalog ought to come first. But is
anyone here familiar with open source content federation software that
actually works? A quick bit of Google searching reveals only Coral CDN,
which definitely won't work for our purposes.

Actually, Paul pointed out (and I agree), that taking advantage of
geo-locality might actually provide significant optimization to the
distribution network. So it's not necessarily that simple.

I agree that long-term management will require some kind of process to
be elaborated. I strongly suggest that, if we're serious, this mailing
list should nominate and constitute a Project Steering Committee to
outline such a process (preferably one as simple as possible) and
empower trusted individuals to do the work.

(by PSC I mean something like

Please amplify on these points? Thanks!
