i have one potent, anecdotal data point:  a friend of
mine is a 3-letter executive at one of the older/bigger
PKI vendors.  he surprised me in a recent conversation,
by mentioning that essentially none of his company's
customers are using PKI for signatures.  actually, he
may have said, "_no-one_ is using PKI for signatures."
he says that practically all of the certs are being
used for negotiating symmetric session-keys.
