There was something called the "server loophole." The language of 
GPLv2 only requires source to be distributed if the binaries are 
distributed. The Affero GPL was created to close the loophole, 
requiring source to be made available even if the binaries aren't 
distributed. IIRC, GPLv3 requires the same.
