People who can't access the CVS ports because of firewall outgoing traffic restrictions need to talk with their sysadmins about the uselessness of such restriction, and the constraints it imposes on us.
I am sure they have tried to do so. Maybe some succeed in convincing their sysadmins, while others have failed. Do you have any advice to offer for how they can say to succeed? Should I ask Emacs developers who have had this problem to do something with you?
