It's not *very* expensive. In one of our products everything is 
protected via what I call "split capabilities" such that individual 
method invocations, fields, buttons etc. are all controlled. The real 
trick is to compile to a "resolved security matrix" on a per-user 
basis to allow short-circuited permission checking.

The checks probably adds 2-4% to the overall runtime in a JAVA 
environment, and could be made much faster still.
