Hi,
how about adding the possibility to give a Basemap instance to the
resolution parameter when creating a new Basemap object, and to
directly set some of its attributes (like coastsegs, cntrysegs, etc)
thus preventing from computing them?
It may be interesting when plotting several equavalent maps with fine
resolution.
It's easy to do it manually once you now all needed attributes, but it
would be better to have it natively integrated.

Stephane: The boundary datasets associated with one Basemap instance cannot be used with another (at least not in general). The coordinates of the boundaries are transformed to map projection coordinates, and clipped to the map projection region. So, if you have been doing this successfully, you've been lucky.
However, you can and should reuse Basemap instances, to make multiple plots on the same map projection region. You can even pickle them, to reuse in other scripts.
