Just a couple of problem that can't be solved in such way:

* problem is not only in activities itself but also in dependencies
  (some sugar distributions might have them but other don't)
  the only way for ASLO is bundling them all

* binary based activities that are strictly depends on particular distro
  version (eg TuxPaint being built against fc9 crashes on fc9+updates)
  it is nightmare to try cover such questions on ASLO

* collections are more users' method, so if one user decided to create
  new collection, he will break any QA efforts because can add arbitrary

The way I have in mind is using Bazaar to cover all technical questions
(development and QA related) and keep ASLO as a frontend for Bazaar

At the end, ASLO might have all activities hosted on Bazaar
(for effectively solving issues w/ dependencies and binaries). Each ASLO
activity will have a source, i.e., Bazaar project.

(We should have a possibility to have bunch of versions of the same
activity at the same time, eg, results of experiments of doers.)

So, users can filter all activities (not only in plain list but in their
collections as well) by source project. If sugar deployment created
"New Deployment" project on Bazaar and linked/branched/created-new
activities there, all their users can download only these activities
(if they want to get QAed stuff).
