I can suggest a scheme where a fee would be attached to the message,
and the recipient would be able to get the money only after having
read and understood the message.

For example, you might receive the following message (it could be encrypted
by your public key to preserve the cash from the MITM):

Dear Jim,

Here's one cyberdollar for you. It is "locked" by an encryption key. The
cybercoin is encrypted by an IDEA key and you can find out the key
by reading the message below:

@ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ 
Valentines' day presents at www.cheap-stuff.com!

An ideal Valentine's day present for your significant other, at a 
reduced cost for you! You can buy your loved one a thousand used 
condoms (mint condition) at a reduced rate of ONLY $5.95!

Visit us at http://www.cheap-stuff.com/cgi-bin/condoms/key.cgi?name=jimbell
to get your postage!
@ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ @ 

The encryption key is located at the URL above.

My opinion on this: I personally feel that this scheme is the way to 
go for spammers. Obviously, it is possible to build mail readers that 
would verify some kind of trusted signature on the attached postage, and
would highlight all such messages. The meaning of signature is "these
people are not crooks, there really is an encrypted dollar there".

Clearly, spammers who pay their readers to read their messages (and who
do get them to read) will have a very high response rate. That may 
justify adding postage to their letters.

The advantages are obvious. The disadvantage is a possibility of someone
stealing the money on the way, if the letters are not encrypted.
