I don't think there's too much subtlety involved. Obviously (to me),
robots.txt needs to be respected. Those links will simply not be
automatically checked for validity.
Sometimes the reason a link dies is because the site _has_ "gone away".
I understand that a temporary outage creates a false positive, but I
think this kind of tool would be very useful nonetheless.
You'd probably need tools for administration of this (so it could be
unset, or set, manually) - but it could be done through a special tag,
too. Make a rule that tags beginning in "special:" (or whatever) are
reserved for special use by the system. Just flag the dead links with
"special:dead" and you're done. (In this case the special use could be
addition of class="dead" to the LI tag for this entry. A CSS rule could
dim it or something.) Remove this tag to restore the link. Thus no
extra admin features are needed, just tag management.
