||Huh? obviously I am missing something here.  It seems to me that by making

|   No, you don't have 640 X 200 virtual pixels.  You have 640 X 399 screen
|locations which can hold a pixel, which pixel is two lines high. For example:
|
|Screen lines -->  X.........   Note the pixels are composed of two dots (what
|                  X..X......   are normally called pixels), and that adjacent
|                  ...X..X...   pixels can overlap by one line.  This means 
|                  ......X...   that the ONLY structures on the screen which
|                               will lose resolution are those which are 
|made up of only one vertical dot.  I would like to see someone construct
|a high-res font which uses this principle - I think it would look GREAT!

It may look GREAT, but it will not solve the problem I posed originally:
you won't be able to get twice as many characters vertically in the
interlaced mode. To get lots of information on the screen, you NEED
640x400 without any constraints or tricks, and without any flicker.
