I happened to be looking through some things when I came across this mailing:

http://lists.fedoraproject.org/piper...ay/007254.html

============As a byproduct this will also enable use to do proper and simple
multi-seat support.==============

Here's the feature:

ConsoleKit Removal/Automatic Multi-Seat Support
http://fedoraproject.org/wiki/Features/ckremoval

So ConsoleKit is the last remaining obstacle to multiseat then. Perhaps once Fedora 16 is released, we'll see multiseat in action in a review from Phoronix. :-)

Especially if it will be simple to do. That's nice.
