Agreed.  But then again this already applies to credit cards (interest is

Quite a bit of work has been done and continues in this area.

"Within the NetCamo ( Network Camouflaging ) project, we study how to
prevent traffic analysis in mission-critical QoS-guaranteed networks."

Some of the people from this project gave a talk at the USENIX Security
works-in-progress session on "a quantitative analysis of anonymous

http://www.usenix.org/events/sec01/mcdaniel_wip.html

Roger Dingledine and Paul Syverson have a recent paper on reputations for
