You've got me dead to rights on the 3rd one, but you don't seem to
understand 1 & 2.  With VNC, I have to login, start the VNC Viewer, and
do all my work inside of that VNC window.  

Besides that, to have persistant VNC connections, you must dedicate a
port per user in the persistant mode.  It has a second mode that allows
for the 'Normal' X behavior.  I.E. You connect, see the XDM prompt, and
login.  Then your session is closed when you disconnect. 

If that doesn't illustrate my point well enough, you'd be best off
trying out VNC (very simple) and you'll understand the benefits and
drawbacks of it's design (drawbacks I've mentioned relating to X).
