DMCA issue is rather ISP problem, not an end-user one. I'm not a layer
(happy smile), but it seems that if ISP-own equipment able to distinguish a
specific content, under specific conditions they are liable to provide
filtering and other DMCA "safe-harbor" features. It will be a case even when
a small part of clients includes content identifier into "optimization"
request (regardless if ISP has or has no installed cache servers)

My main point is that separating "optimization" and "discovery" processes we
can eliminate all those issues all together, making ALTO more flexible and
ISP less reluctant to deploy it ( or part of it).
