First of all, I'd like to see some operational experience with TCP-AO.  
Don't throw away your old shoes until you know whether the new ones fit.

Second, it's not like TCP-MD5 isn't being used. As such, "historic"  
wouldn't apply. "Deprecated", maybe.

Third, why is it exactly that we can't simply move from MD5 to IPsec  
to protect BGP sessions??
