Considering these facts about 1/2 year ago I chose
James as an implementation basis for a very similiar
project and found James very suitable. (which is a
reliable solution capable of all those nice exception
cases which I could never program myself) BTW. thanks
to all james developers!

Understanding concepts of James ate up almost half of 
development time. :-)

The challenge-response-payment idea was IMHO first
discussed in "Pricing via processing" (Cynthia Dwork,
Moni Naor, 1991). 

You can find the paper here:

TMDA is one implementation of that idea. At the moment
the "beloved" company Microsoft is heavily researching
in this field.

However, my guess is next version of windows will
contain this feature.
