If so, that's completely unrelated to my draft. The counter-measures 
proposed in that draft don't have to do with TCP sequence number checking, 
as TCP seq number checking is mandated by RFC 793 when you process TCP 
segments.

No, it's just that the draft was updated. Use the "Search I-D" link in 
http://www.rfc-editor.org and search for "draft-ietf-tcp-secure" . Or visit 
the TCPM WG web page at http://www.ietf.org . (That's another reason why I 
keep my drafts at a personal web site, BTW).
