Multiple simultaneous physical (graphical) sessions didn't really work, 
at least not without a lot of careful hand-configuration and even then 
the secrity between them was quite brittle due to requiring a lot of 
things to run as root.

Two features in particluar made this work more recently -- proper cgroup 
support up and down the stack (eg systemd/logind in userspace, and 
more kernel subsystems implementing cgroups properly) and KMS allowing 
for the X server to not have to run as root.

(Personally I think the whole idea is a bit daft, but evidently there 
 are a lot who disagree with me...)
