OK.  I have not, but I haven't used the newer Cortex-M cores as yet, so 
it could well be a new feature.  It could also be an option which the 
mainstream microcontroller manufacturers don't provide.  Which ones have 
programmable windows?  And is this something that will be common, or is 
it just something that a few manufacturers with "architect" (if that is 
the right term) ARM licenses implement on their own?

(I know this is off-topic for c.l.c., but I'm interested in there devices.)
