With the database schema changes that already landed on db-devel package
set names cease to be unique globally i.e. a package set names are now
only unique in combination with a distro series.

That breaks the existing package set naming/traversal scheme.

In order to fix the currently broken traversal scheme for package sets
and have a working LP API after the roll-out on 04-Nov-2009 I will need
to land a branch that adopts the URI structure above (e.g.
/package-sets/karmic/kernel-packages) today.

Having said that, I am wide open to discussing package set URI/traversal
changes for the forthcoming LP developement cycle.

Good question. I understand we'll be only using them for Ubuntu in the
immediate future but may well decide to use package sets for other
distributions at some later point in time.

This is an interesting question and reminds me of a question Curtis H.
brought up yesterday.
What happens in a case where we have 2 distributions A and B with an
identically named distro series X and both requiring a package set
named 'kernel-packages'?

In such a case our current package set naming/traversal scheme would not
hold up.

Another good question. The emphasis so far was on providing package sets
(and archive permissions based on them) via the LP API in order to
facilitate the distro team's archive re-organisation effort.

Maybe Michael N. can comment on this..?

Best regards
