Of course, backreferences are being used in LZ77, so I'm not claiming anything in my draft is in any way new. > Maybe Deflate could be considered for the ICMP compression. As the half-draft says, I thought about that. Too complicated for my taste (even if you take out most of the gratuitous choice that is in RFC 1951). > Nodes may need Deflate code anyway, either for HTTP compression or X.509 > certificate compression. I'm mostly thinking about nodes here that are too limited for either HTTP or X.509. While deflate is not *that* complicated, the eight specially crafted bytecodes are about two orders of magnitude simpler. (Maybe one can make them even simpler, but I didn't invest much time in this demonstration of concept.) I should probably also clarify that I wrote this draft to un-stall HC, not to add complexity to ND.
