There were a couple of problems with that, but here's what I tried:

$MODKEY-w)
      if wmiir read /www 2>/dev/null; then
            xwrite /ctl view www
      else
            firefox & #firefox not running
      fi ;;

This isn't really what I want, though. Instead of being task-oriented,
the tags are application-oriented. So, for example, I can't have a
setup like above for firefox and xterm, and then display an xterm next
to a firefox window, switching back and forth with mod-w & mod-return.

Yes, actually. ;)

I evidently didn't poke around hard enough before. The tools for
switching around between windows are all there, it's just a matter of
putting them together. I've attached the result, for anyone who's
interested. It allows you to say "go_class Firefox-bin firefox", and if
there's a firefox displayed somewhere you'll be switched to it,
otherwise it will be run. It's a bit brute-force, I'm afraid, so it may
not scale well for folks with lots and lots of windows. But it does
seem to work. (TODO: repeated invocations should cycle if there are
multiple matches.)
