Someone brought it up on the IETF HTTP working group list a few weeks ago,
but noone could come up with any particularly good reason for it. This'd
be a good reason, but establishing actual URI forms for distributed
content would be much better.

The trouble is implementing MD5's of each object, and all the varying
forms; especially on dynamically generated content which is "actually"
static. All an MD5 hash of an object here is, when you think about it,
is an informal URI anyway..
