I saw reference to having patches for DBus available. How much are you working with kernel, dbus, DEs, other security model implementers, and Distributions?

Are they willing to merge the idea? the implementation? It could be a huge cost if upstream requires backwards incompatible changes to be accepted. It is also a huge cost to Nokia and the users to always be running a fork.

Are desktop distributions interested in using the security model? Is there interest or consensus from other security implementers (app armor, selinux, etc?
