There are several to achieve that but remember first that Arch being a
distributed system, there are several repositories, all equal.  The need
that we have to have a blessed one (for integration, release, and so on)
would be represented by a special archive (hosted on repoman) managed by

Yes.  It even records permissions changes.

Dsitributed meaning that anyone can branch out of any archive and work even
on a laptop on a plane, committing to that archive and merge afterwards
with another archive for "publication".

This is tremendous work as Arch and CVS don't manage modules the same way
and I don't have time to do such benchmarking :(
