heh. It shouldn't be a guessing contest, you could have asked for in depth
comments :). Btw, your diagrams indicate you understood it correctly.

Note that that is also true for my system. We are displaying the same thing, it
is just the numbering that varies.

No, x and y are independent, as you can fx see in my own example (6x7).

strange.

Actually it would be very simple I think. Just a normal overview map wrapped in
two dimensions and rotated 45 degrees.

I prefer my solution because it preserves the planar assosiation between tiles.
Very little would have to be changed in the server.
Also, actually using the tiles would be easier because of the planar
associations (IMO).

But note that you diverted from my original drawing on a point: you modulused
the x values with the map xsize. You shouldn't do that! Take fx the tile (4, 1)
and go -1 in the x direction. That will give the tile (3,1). That would be 
beyond
the map, and with my numbering there would not be any tile with those
coordinates, and the tile could easily be tested for existance. That is not 
possible with
your modulused numbering, which is a fatal flaw.

When you think my numbering scheme is confusing just tilt your head 45 degrees
:)
