IPsec is mostly inside enterprises, so actual deployment can only be
counted by asking the vendors (who won't say) or the open source
providers (who don't have reliable numbers).

I don't know what part of encrypted email is done by individuals and
what part is enterprise. But since email in general is becoming less
and less cool, I suspect email encryption will over time become more
of an enterprise thing, and therefore even harder to measure.
