Speak for yourself? :-).

Your use of the word "unfortunate" is unfortunate in and of itself. :-).

Not true. I claim that the closer you get to a cheap, instantaneous,
electronic, book-entry settled transaction over an insecure public
internetwork, the closer you have to frontload the authorization, the
"signature" of the intermediary in the transaction. In fact, that's the
most important part of the transaction, the reputation of the transaction's
guarantor. You end up with a cryptographic object which whose only
information component is the value of the asset and the guarantee of a
financial intermediary. A digital bearer certificate, in other words.
C'mon guys. Why do you think that DigiCash calls it's cryptographic objects
"coins"? Why do you think that MicroMint calls itself a "mint"? Why do you
think that Millicent calls it's "tokens" "scrip"? It's kind of hard to talk
the talk unless you're walking the walk, most of the time. At least in
private enterprize.
Wake up and smell the coffee, here. We're talking about digital *bearer*
transactions.

A rose is a rose is a rose is a rose. If it quacks like a duck, et cetera.
Sheesh.
