Are you familiar with Systemics Ricardo system, which uses Ricardian 
contracts to implement the concept that you call "vouchers"?

	<http://www.systemics.com>

This system has been around for about 5 years and has been used in the 
fields of currency, stocks and bonds. The use of "Ricardian contracts" or 
"vouchers" is a critical part of the architecture.

I've copied this mail to Ian Grigg from Systemics <iang@systemics.com>, 
because I think it may be worth you both engaging in some dialogue.

We're in the process of integrating their Ricardo system into our 
CashBox(tm) system, and I'm interested in knowing about any other companies 
who may be implementing other payment systems based on these concepts, so 
please do let me know when others do implement.
