Hi Martin,

Looks like a good feature. The LEP looks good. However I am concerned
about 1 thing in this workflow:

Some (only *some*) packages need extra build deps just to run bzr
builddeb -S . Since that command will be run on buildds having all
build-deps installed (please correct me if I am wrong), building and
uploading a package would eat up more resources, since the buildds would
need to be called twice: once for packaging the source from the branch
and once per arch for building it .

Not a big issue, but something that might cause build delays during mass
syncs, package rebuilds, etc.
