About 2 seconds after I sent that message I realized maybe I should be
thinking about this at a lot higher level... and that I should have examined
Ville's js before responding.  :-)

Now I'm thinking something like:

w3_linkcheck.addLink(link)
w3_linkcheck.updateLinkStatus(link, status, message)

Inside the methods we can handle the details of translating the link to an
id using the same method Ville uses (md5 and prepend with L or S for link or
status), inside we could set the appropriate status class to the cell in the
corresponding row: class="status_200" class="status_301".. have the perl
script output the messages directly in the js, or figure out a more complex
way of handling the messages so the size isn't inflated too big.

On the right path now?
