I did something similar to this in JS alone:

  <http://toolserver.org/~river/recentchanges/>

It requires 1 request per second to update, but the backend is a C++
FastCGI and the database query is trivial, so the requests create no
noticeable load.  I imagine it should be fairly simple to do something
similar for a plain number-of-edits counter.  (You would only need to
return number of edits, rather than the edits themselves, so a little
less bandwidth would be used.)
