David,
AOS also has a separate RPM repo (one of several actually), that being arcanoa-sub, where I believe the intent is to eventually locate various packages that only those with software subscription are entitled to.
Now, do not hold me to all of the above being 100% spot-on, but right now that repo only has three packages in there: couple of printer "drivers" and a utility install application. So I think that's very much work in progress at the moment.
