Another requirement of the Gemini Project is to be
able to dynamically change access to various records and
fields. If my understanding is correct, you can do this by
calling a special routine from a SUB record which re-initialises
access security by re-reading the ACF.

What would happen, under these circumstances, to a "dm" display?
This change in access security could well mean that
controllers which previously only had read permission now 
have write permission as well.

Could "dm" be made to update dynamically? My feeling is that
it could, if it were only displaying simple text like "Access denied"
and didn't require redrawing of boxes with different colours.
