Would say that nmap (http://www.insecure.org/nmap/) is the best of the
portscanners.  I'm sure you can run the non-stealth parts of it as a
user.  Though reading the progsoc AUP again, I would say that having
anything like this in your account is sufficient grounds for you to be
first up against the wall come the revolution...

You would (I think) have a hard time finding any law which prevents Optus
offering the service only to Windows users.  In the absence of such a
law whatever they write in the contract is how it is.
