I have now gained some more experience on the use of my Asus Eee. It really does work a treat. I especially appreciate the VGA out, with its accompanying software. This allows you to go up to 1600 by 1280 pixels and will clearly show you which of the screens you are sending the signal to. (Beats banging on the Fn F5 combination and waiting for the beamer to pick up the signal).
I have also got the Utrecht University VPN working. I have not used the Cisco VPN client but installed VPNC. It took some puzzling and if I can find the time I might write it all down. If anybody is having troubles, do contact me.
