I really like this also. I don't like the parameter name (how about
"inherit security" instead ?) but other than that this seems to be
the best option.

Ok - I'm beoming convinced that setting "inherit security" should
override force mode if not set to "no". This is starting to make
more sense.

Yes, it is definately a win.

I'm out doing talks until Sept 12th or so, and will start
on coding this up for the next release (or maybe target
2.2.x) once I return.

The discussions on this are *really* helpful !
