Yes, I'm working on one, and it's running, just not finished.

You don't need to modify the MacApp Sources, but you have to override
a couple methods, but not too many. I don't know them out of my head.

The basic idea I'm using are cohanders. You should
look into the TEvtHandler implementation to learn more about it.
(a cohander is a subclass of TEvtHandler)

Another source to give you some ideas is to look into the very old
AppleTalk Demo Application that was shipped with MacApp 1.1. Don't
use any of the AppleTalk stuff in there, since it is completely
outdated, but the theory of operation is interesting.

But on the whole, I would love to have the CTB supported in some way
in MacApp since I'm not really sure about everything I've done.
