Multiseat is available, at least in beta.

I've been running multiseat based on nvidia binary drivers for quite a while.  
It's an unsupported configuration but it works quite well. I'll try to get 
some time and document what I've done.

It's not hard.  I do some udev magic to ID the keyboard and then it's a piece 
of cake.
