Well, whether people will use it or not is their decision.

If they want to give it a try I don’t see any harm why ipsec should 
not start.   It’s a lot more likely to work than some firewalls, given 
I used it years ago under vnet to debug ipcomp problems.

I think in order to not waste more time on this, can we just MFC the 
change to 11?
