A note on the ESP SPI overloading trick, such as used in
draft-ponchon-ipsecme-anti-replay-subspaces for which SSH
has IPR, they submitted an IPR statement:


See https://datatracker.ietf.org/ipr/5880/

 	In the event that any claims of the Subject Patents are necessarily
 	infringed by such future version of IPSec (“Essential Claims”), SSH
 	agrees, upon written request from a party, to negotiate with that party
 	a non-sublicenseable license to the Essential Claims under reasonable
 	and non-discriminatory terms and conditions, taking into consideration
 	the other technologies implemented in the same product, solely to the
 	extent necessary to implement required portions of the Future IPSec RFCs,
 	provided that the party grants a reciprocal license to SSH and provided
 	that the license terminates if the party initiates a claim of patent
 	infringement, directly or indirectly, against SSH, its subsidiaries,
 	or its affiliates.
