NX from nomachine or any nested XServer, e.g. Xephyr

Yes, you wouldn't even need SSH, you can just export the DISPLAY and make sure 
the other user is allowed to connect to the XServer (see xhost)

The problem with a full session, e.g. the one started by startkde is, that it 
includes certain services, e.g. window manager, session manager, which 
require to be the only one of their kind per DISPLAY.

Since your usecase is two users on the same machines, I'd recommend going for 
a nested XServer approach. This is very common among desktop developers, e.g. 
running a development KDE 4 session inside a KDE3 session [1]
