So, I've written a program that does something similar to this, for
dzen2.  Basically, it takes the output from xmonad, and adds in the
date, battery status, and whatever else you can think of to the actuall
input to dzen, thus allowing you to customize the output a bit more.

You can write new things to have it output via a simple plugin api (in
haskell, of course).  If you're interested, I would be happy to
cabalize it, and put it up somewhere.
