This is kinda tricky if the windows in question don't exist at  
startup, no?

The correct way to handle it is to support session manager  
integration:  on exit, save the serialized layout in the session  
manager as a -layout option; the session manager will then restart  
xmonad with the specified options, at the same time that it restores  
the other programs in the session so that all the windows in the  
layout are (hopefully) also recreated.  But then xmonad needs to know  
to hold on to it until it at least has the windows explicitly  
mentioned... and, does -layout work by windowid, or by class/name/ 
role?  windowid is a nonstarter across X11 server instances/ 
instantiations.

See XMonadContrib/SubMap.hs.
