Basemap questions

Hi,

I have two questions about the basemap toolkit:

1) I use the orthographic projection often in my research. Can support
for this be easily added to basemap?

2) In the basemap.interp function, which just forwards the arguments on to
numarray.nd_image.map_coordinates, why is it necessary to enforce regular
grid spacing? It seems to me the interpolation will work either way.

Cheers,
Curtis
