A friend of mine has examined the 'Cogito ergo sum' reasoning and concluded
it was based on faulty presumtions...

Yes, of course. Optimization thru faith. But: this is an implicit trust. One
_could_ think of an architecture where even this had to be made explicit.
Gerck (once again...) uses encryption as a 'routing' mechanism: distribute
encrypted data freely, only the correct recipient will be able to open it,
and the recipient would always be sure it was from the right sender...

Yoda: "No, there is no 'try'. Either you do, or you don't." (or something
like it)

Hmmm... actually, trust is a multidimensional vector, consisting of all the
trust-points.
