No, not today. Perhaps in our next release.

In the meantime, what most people want is simply to have the desktop 
resize automatically upon hotdesking. That also may come in our next 

For 4.1, I've attached a small script I've written which does this. It 
won't work for multihead but it works for typical cases.
To use it, simply launch a utaction in each session at startup which 
runs this script upon every session connect:
utaction -c utfit &

For Linux, you should replace the "nawk" instances with "gawk", and you 
may need to tweak PATH to add some directories for Linux.

If anybody feels like enhancing this please feed back your work to the list.
Useful additions I'd like to see but don't have time right now:
- platform independence (i.e. choose nawk vs gawk based on Solaris vs 
Linux and an all-inclusive $PATH)
- multihead

#    sleep 1; pkill -HUP gnome-panel

exit 0
