I think it sounds reasonable.  I've built several web apps that work this way or 
similar to this.  I typically build all the logic into the structure of the 
database and then design queries that return, for a given user, everything s/he 
is allowed to do.  That makes it simple for the application to decide which 
buttons and pulldown menus to show: it just shows every action returned by the 
query(s).  I think it's a good design decision to keep this logic in one place, 
especially as the application gets more features.  In my case I make the 
application dumb and the queries smart.
