The gray area of port-scanning legality came up at Usenix's
conference earlier this month.  I believe the consensus was
that you are on firmer ground when organizations who own
machines that attackers might perform port scans FROM 
have AUP's that prohibit such activity.  Nothing in this 
court case would seem to prevent an organization from 
disciplining individuals for using a system for an
administratively prohibited purpose.
