Yes, this way makes more sense and in fact I've started investigating it 
already.
To make debugging easy rather than replacing user32.dll I'm using 
Windows hooks
to try and catch all the function calls and log them first ... then 
we'll know which
ones to work on to get simple apps going ... it also gives us the 
ability to call both
the original user32.dll function and a modified one which will do 
something with X
which might be useful in debugging. Not much progress yet, just got the 
hooks working...
