Biz-dev wankery. This is only of interest to VMWare's customers, so that they can name-drop Docker.
I disagree. There is a bunch of really talented people working on CloudFoundry (I spent 7 months at CF). The day that docker was released, we were talking about how we could work with it and integrate it into CF/Warden. Sure, there is a bunch of the biz-dev stuff baked into it, but that just justifies having all those smart talented engineers focused on building cool stuff and integrating all these projects together.
