I read a Sci-Fi book that seemed to have a good idea. Everyone could set the price for recieving Email. You would pay that price to send email to that address. If someone sent a message to your $100 box, you would tend to pay attention. If they sent it too your 5 cent or 1 cent less so. You could then do a reply to cancel the fee. This still has some problems like address spoffing, money landering, ect, but it does seem to be a possible start.
Why let the goverment in,
can't we be greedy too.
I don't remember the book name, but it was about a Beserker type device attacking earth every 5 years. Not a "Beserker" Beserker
, but a planetoid machine like the Saber...n kind.
