IMO, you did define "garbage" in your reply to my previous post:
1. Royal pain over NAT devices (except when using the new NAT-T).
2. New protocols for no good reason (now fixed with ESPinUDP, in other
words now using UDP as it should have all along).
Frankly, I much prefer CIPE as a much better design, IMO.
