Thanks guys, your putting forward good ideas and suggestions.

The username/password combo on two separate networks is something that I hadn't thought of, so something to bear in mind as I'm doing my own testing.

Thankfully there is NO access to any USB ports anywhere on the network (not even USB mice) so that is a small bonus when it comes to watching camera's, usb sticks, ipods etc. Likewise the BIOS's are locked down, but I alwas see that as a week link... out with the battery and hey presto, they're in

Anyway, thanks again, and any more suggestions would be welcomed.

Cheers,
Ross.
