Summary: One minor issue to discuss

Major issues: none

Minor issues:

Section 2:
  As can be seen, the WESP format extends the standard ESP header
  by the first 4 octets for IPv4 and by 8 octets for IPv6. The
  WESP header is integrity protected, along with all the fields
  specified for ESP in RFC 4303.
Normally ESP wouldn't need to process encapsulation headers that
appear prior to the SPI.  Won't this require modification of the
ESP implementation, possibly breaking its modularity?  Would
it be problematic for certain algorithms to include this data?
It might be good to state that.
