We don't have anything specific so far, we just put basic udev
infrastructure in place, no implementation of such features.

We will come up with the udev managed ACLs, which will use udev rules
instead of HAL fdi files. The "seat" thing will probably just a
special-case of the user ACLs, and we will keep that in mind when we
come up with a prototype for the udev/ConsoleKit ACL management. For
now it's nothing but the collection of ideas how to possibly do it.
