By experimentation we determined that turning off window scaling meant
we didn't trigger "Treason uncloaked" on remote systems.

The recent posting about passive OS fingerprinting led me to

http://www.openbsd.org/cgi-bin/cvsweb/src/etc/pf.os?rev=1.21;content-type=text%2Fplain

which says that Googlebot has window scaling turned off, too.

Things that make me go, "Hmmm."
