I am dubious that we can solve this problem in a week or two. :)
Did you have in mind just a survey of the issues involved and a couple of
'this won't work because of this' examples?
It seems to me that if you want remailer operators to be 'paid' as
incentive to continue being an operator, then you're going to need
to use digital money with 'real value'. Does that necessarily imply an
infrastructure for turning that 'real value' into dollars, or can we come
up with some alternative (local) currency that is sufficiently useful?
