Joe: 

I have come to the same conclusion that an open-source TCP-AO is the next
step for TCP-AO.

I still hoping for some fairy dust ... to fix the BGP TCP security problem. 
If you have any ... let me know

It is available in Cisco IOS at least. Its biggest drawback appears to be a
lack of open-source implementations.

Given the problem with TCP-AO deployment is that there is no free
implementation and low implementation by vendors, how exactly would a new
solution with even less implemented code help?
