I finally had a chance to get back to this thread and review everything that Matthew, Torkild and Mike sent. There is a good amount of documentation on both EBR and Package Drone at [1] and [2] respectively. The recording of Gunnar's presentation for EBR is also very educational.
I'm very excited about EBR now and I see exactly how it will fit into the system I've proposed. So I think our ORNL team will have to give it a try. I'm having a little trouble understanding all of the features in Package Drone because it seems to do everything, but I *think* it could be used to publish the p2 repository created by Tycho with the bundles made by EBR to a centralized repository somewhere.
I think some combination of both of these would then get us in a position that we could deploy bundles to both the Marketplace and a repository to be used during development. I noticed that Package Drone also supports .deb and .rpm, which would make it possible for us to deploy native artifacts as well.
I'll keep you posted as I try things out.
