Fun example! Welcome. Congratulations on getting investor funding. 
I'll be interested in how your beta launch unfolds.

I agree with your premise that direct sale of digital content for 
micro amounts is a potential disruptor for world information flow 
(publishing of all kinds).

What occurs to me, in the context of this list and the W3C IG effort, 
and its associated Credentials effort, is that perhaps we've reached a 
parting of the ways.

Specifically, my thought:
Maybe the system that sells digital content on the web for 
micro-amounts will be so different from the one required for movements 
of large amounts of money that attempting to develop both together is 
unrealistic.

In other words, what you're doing may be easier, you may have already 
done it, and the people in this list may be working on a substantially 
different problem.

Thoughts anyone?  Have I jumped to an unwarranted conclusion?
