I just don't think that's as >practical a proposal if the goal is to change providers' behavior. We're fooling ourselves if we think 'writing a spec' will change provider's behavior. If you want to provide enticements, why not just implement some good statistics gathering tools that allow periodically turning off caching, and analyzing projections from the data so gathered? It's a lot simpler than all of this fol-de-rol in the proxy caches. There's other kinds of sampling, too. For example, you could selectively turn off caching for randomly assigned host addresses e.g., hash the host name, and day k of a n-day cycle, turn off caching for hosts whose hashed IP address mod n == k.
