I have been thinking recently about introducing a kind of "status" 
object into each module.  The LCD code, or anything else interested in 
current module state, would then read off the status object and format 
it appropriately.  This would also make it possible to build palm pilot 
or web type status monitors and perhaps remote controls as well

The status object would probably fire an event when the main code made a 
change, so that interested receivers could do their updates (like the 
LCD screen).

Any thoughts on how to do a generic status object which is then 
subclassed for each specific module?  How does this sound for an 
approach generally?
