I wonder the same thing. For instance, using PHP, I suppose I
can go to codeview and display certain menus depending on whether
the person in logged in. (Example: why display the "log out" menu
when a person isn't even logged in? The converse is also true.)
I'll have this figured out in the next couple of days (weeks?)
After all, the Spry Menus are just JavaScript. I suppose if session
variables are active, you can display any menu you want, depending
on whether the person is logged in, and what kind of access you
give them. I just haven't gotten that far.
