The correct answer is not yet. Currently VNC support is a hack and does 
integrate very well. Since VirtualBox 4.0 there is a new plugin API 
which allows
to write a VNC plugin that integrates the same way as RDP but without 
the GPL
licensing issues. Someone already started writing such a VNC plugin but 
work has stalled. It's more or less in a working state so they plan to 
it at some point in the future.

We have an highly experimental port of that code available for vbox 
4.0.4 but I
don't know if we ever got it working. bapt@ has done some work on this 
so probably
he knows something about it.
