I do hope you have some seriously good lawyers should MS regard this as a=

libelous statement! It's missing the word 'allegedly'!

More seriously, George Foot's excellent paper made me realise that we are=

established before keys are shared, with public key systems that attempt =
to
(1) replace those systems and (2) provide a mechanism for knowing who you=

are talking to (aka 'trust'). Perhaps they can't. What is certain is that=

technology on its own won't do.
