Ah, no, nothing is stopping us from keeping the pool architecture for this,
just having different views of the stuff for different mirror networks to work
on.

Well, it just calls for smarther mirroring tricks.
Also, i do believe that not all mirrors carry experimental for example, and
said packages are in the pool all the same, or whatever.

Yeah, that would be easiest, i was speaking about a logical separation of the
arches, not a physical one.

Thanks for your input
