IMHO that's the most straightforward approach.
He can use masked array for empty blocks (if contour data doesn't
already contain the holes as masked array) and apply inpainting, then
draw the land.

warpimage() as it is now, checks if passed image is url, so we can add
additional check if image is url, with urlparse to deduce image coordinates
and projection if present, then overlay it over already created Basemap

Assuming IPython in pylab mode:

I think that paths needed to be passed to CPP/LDFLAGS like this:
CPPFLAGS=-I/usr/include/hdf LDFLAGS=-L/usr/lib ./configure --enable-hdf4 && make

installing it globally would break possible dependencies in any
