This was just sent to the IPsec list.
Does this pattent "read" on FreeS/WAN / Openswan opportunistic
Licensing offered is "Reasonable and Non-Discriminatory License to All
Implementers with Possible Royalty/Fee" which sounds bad for open source.
That pattent was filed 2006 Aug 18.
Abstract (which means little to me):
A system and method for failure recognition is disclosed. The
technology initially establishes a security association (SA)
between a client and a first server on a network. In addition, an
active reference count of a number of connections in the SA
between the client and the first server is maintained. The SA is
evaluated when the active reference count returns less than two
connections within the SA between the client and the first server.
