Sorry, I did not see the scope of your question.

For clipboard transfers, I expected that vnc has no clipboard transfer, 
at least it did not have it in the past. From a sysadmin point of view, 
I did see that as a security advantage, not a usability disadvantage.

For keyboard transfer, I experience no translation at all. If I type a é 
(as in my name) on my msWindows desktop, I get rubbish in a hp-ux vnc 
session. For this reason I have the language/keyboard selection enabled 
and switch between 'us-international' (my msWindows default) and 'us' 
for the vnc sessions (and ssh, and telnet and such).
