Probably just a good pipedream someone had a while back and is likely just circumstantial / coincidental to bitcoin, but I suppose it's possible he later developed the ideas, but without a detailed explanation of the technology behind it I'm sure many people have proposed the idea of a digital peer-to-peer currency before, but it does have the hallmarks of bitcoin. Maybe it took him all this time to come up with a workable solution? Who knows. Interesting anyway.
if you read on he seems to have some idea of how it'll work
"Maybe the community can bypass the old powers (countries and governments).
It wouldn't be a revolution, but rather evolution. Slowly a new p2p system
might take over. The current monetary systems were mainly backed with gold
(not anymore now, to my knowledge). Maybe the underlying values of a virtual
peer to peer system could be other scarce resources, relatively easy to
exchange via internet. Examples are: computer processing power, bandwith and
data storage. These resources would make a limited peer to peer money
exchange system possible. Limited to the total real life value of all these
resources. However from that point other resources could back up the virtual
currency..."
...anyways maybe its just coincidence
(guessing that he started in 2002)
