I do not agree. Xvnc servers are smart enough that for practical purposes
you do not feel any difference. You even can live rotate 3d graphics 
remotely.
Xvnc servers compress data and they send only differences over what 
had changed. Also You can adjust quality, compression level and resolution 
according to
your needs. Security is also not a problem because you can easily tunel 
it over ssh.

I would suggest to try it practically. Few years ago I started to use
this approach  (over 64kb/s line from home) instead of connecting to 
remote kernel. From practical side 
advantages were obvious.

Thought your theoretical considerations seems logical and in principle 
right, my 
personal practical expierence is different: 1)stability,2) you can run 
long jobs 
over night with you notebook turned off. 3) later can connect to the same 
screen from different place (mobility).

Complete control over remote server is also not required. In these case 
just put Xvnc executables in /home/YourAccount/bin folders and somehow 
adjust config files.

Because I have quite large expierence using both methods (remote kernel 
and Xvnc) for quite a long time on different machines (for Xvnc I use only 
linux boxes), now I use ONLY Xvnc approach.
