One can switch the menu bar, as is done in MultiFinder.  One could have
application-specific menus in a bar within the window (as is done in
Microsoft Windows).  One can have a moveable menu bar, or menus that can be
torn off and positioned on the screen (as in HyperCard).  One can work
around the single mouse button by making a mouse sensitive area that
brings up the menus.

I don't think one direction is easier than another.  If you design for the
more powerful environment you probably will take advantage of features that
aren't available in the other environment.

The difficulty (as I understand it -- I'm not associated with the A/UX
project) is getting the exact same code, which is in ROM, and was written
for the Mac O/S, to run under A/UX.
