I couldn't have said it better.
And as it stands, DCC is its own protocol and pretty much limited to the confines of IRC use. In the past, people have attempted such things as FTP to DCC gateways, with some success, but overall without event or change to IRC culture. I'm afraid that such a change to DCC will make IRC clients "Peer To Peer Ready" and, as you said, the target of media rights giants.
Internet Relay Chat is just that.
