Huh?
rel-tag is for self-tagging. For tagging arbitrary urls, you need
xFolk or hReview.

No, if this theoretical search engine were like technorati's
implementation, it would turn up "things that mention pepsi and are
about crap".

Um, I think you've got things backwards here. rel-tag and rel-
directory are for precisely this purpose (as were meta-keywords, but
those have problems).
First of all, <a href="http://www.pepsi.com" rel="tag">crap</a> is
invalid, because the tag is the last component of the uri, not the
linktext.
Second, assuming the previous link were valid, ie the url was http://
www.pepsi.com/crap, it would be tagging the document which contains
that link as "crap," not pepsi.com.
