I haven't really been following the discussion too closely and I don't
really comprehend the maths and coding involved, but the quincuncial
topology does sound interesting (I can't test it though).

Looking at Ross' diagram I can see how there would be large
distortions in the southern hemisphere and I guess from the fact that
I live in the Southern hemisphere I'm not entirely happy about that
:)  (Besides, Antartica would be a much more interesting place to
fight over than the Arctic).

Anyway, what I'm wondering (at the risk of making everything far too
complicated) is why not have two seperate maps for each hemisphere? 
There would be a 1:1 join along the seam at the equator and from a 2d
GUI POV this would look seemless if the code was up to it.

I guess it would be sort of like having two cones stuck together.

Of course the map for the southern hemisphere would have to be drawn
'upside down' (with Antarctica in the centre) but then many of us
Southern Hemisphereans might point out that all existing maps are
drawn upside down anyway :)
