Hey Andrea!
Just a couple things:

It's not that bad. (1) All feature negotiation options are

yea, but I was thinking if you chain many change X in the same
packet. I'm not
sure that's legal. But anyway, an implementation may process
options from the
tail of the packet to front, and discard any previously seen
feature negos for
the same option.
(1) Implementations MUST process options from front to back.
"Options MUST be processed sequentially, starting at the first option
in the packet header."
(2) "A packet MAY contain more than one feature negotiation option,
possibly including two options that refer to the same feature; as
usual, the options are processed sequentially."
yea, in fact i got "scared" when I wrote the multi-byte patch. the:
if (c == s)
became a:
if (memcmp(c, s, len) == 0)
Yep :)
