The app_server computes this on demand only, and it does so using similar
code to what I posted. It would only be a waste of resources to communicate
to the app_server like that. Much quicker to calculate it client side,
although it would mean to duplicate code. With the addition of "BView*
lookingFrom", it wouldn't purely be a duplication, though.
