Did you know that this is already implemented?
 
WB2.0 has the "virtual desktop" feature allowing you to have a WB screen
slightly greater than 32000 x 32000 pixels.  Do you think this screen is
possible with only 2Mb of chipmem?  If so, go down and try it on your friendly
neighborhood dealer's demo machine and see what happens...
 
All that extra screen memory is stored in fastmem, and then shifted to chipmem
when you scroll the screen...you need something like 12Mb for the full screen
bitmap...
