Hi all,

a while ago, when we considered providing pure Python I/O in GeoPandas, I have drafted read and write functions to and from GeoDataFrames to shapefile using pyshp. We decided not to go that way in the end but I was wondering if you might be interested in including it here before I'll simply dump it to a Gist and forget about it.

You can check the implementation here geopandas/geopandas#1580 . It may be a little dated but should likely work. I am happy to turn it into a PR if you consider it worthwhile, but I am also happy to let it go.
