   Do you HAVE to close the NDAs before swapping direct page
information? If the NDA is an entity in and of itself, you don't really
have to worry about losing information to a DPswap, and I don't know of
many NDAs that save information on an application's direct page.
   All you'd really have to do is save the windows' information and
handles, hide them (get them off the screen and sweep them under a rug
someplace), swap the direct pages, and open any new windows. Desk
accessories shouldn't even enter the picture.

   On another point, we're assuming that the applications that we start
under this theoretical multiple personality environment will follow
Apple's guidelines for tool use, memory requesting and allocation, etc.
I say don't worry. Any application that can't share memory with all the
others in the system shouldn't be allowed to play with them anyway. >:^)
