> Would anyone be willing to give me their serial number for YR, via email? I want to play the game over my LAN, but of course each PC needs a different serial number during installation, or they won't play together :(

I agree with you there. Westwood made a fault and there is no reason to buy an extra cd. But I think you should try asking any person who had their serial banned or something, I think there are few and they won't mind as they can't play online anyway.
