Contributed by grey on from the apparently only Cisco can secure TCP, so pay up! News at 11 dept.
Looks like cisco is trying to bend everyone over a barrel again like they did for VRRP - except now with TCP, by hijacking the new IETF process to work on TCP issues. Good way to ensure that everyone can't implement compatible standards, since free software implementors will not be able to implement this. When will people learn that RAND == NO FREE SOFTWARE. Of course, for all we know the applied patents are for Cat Detector vans, so you have no idea if this is even relevant.
