Finding out how to specify dependencies was part of point 2, for a
reason.

That's obvious - same as experimental today. Don't worry about that
part.

Have a list of packages with versions that need to be built. Or just a
list of source packges and binary packages and build anything missing,
like today for e.g. experimental. And have a common location where the
source packages are. That's basically. (One could specify additional
dependencies / conflicts that are not in the source package.)

Why not just use one location - shouldn't be an issue unless you plan
to have the same packages and version numbers in multiple PPAs. And
that's something I recommend not to do.

All that are in the sources-file specified.

One upload location per queue (or for multiple queues) - one could
always have a backend which changes things.

Why not just upload packages, and build from there? As we do now?
