What is so bad with my CGI example? If I change something in the script 
that will make it's output different but has no semantic importance, I 
use weak etags. - You could argument that it is not worth caching at 
all, but please, get rid of "same second as now"-last-modified headers 
first. And that way the whole weak validator story can go.

(I don't see any interop issues with browsers on weak etag resources.)
