*shrug* I'm a business school professor, and do analysis like the
analysis behind my statement above for a living.  It's a fairly
obvious extension of my posts on use of DMARC by financial
institutions.  And it helps explain why GMail seems to be actively
dissenting, and Hotmail has not followed yet.  Those email providers
have a different approach to being portals, and use different trade
names for their financial activites to the extent that I am aware of
them.  I'm not going to yield on it quite yet.

So, call it "tin-foil hat territory" if you like.  Being an expert on
Internet business models doesn't make me *right*, but name-calling
isn't going to bother me.
