Got an email today with a link to an OSGeo Python Library proposal:

Several OSGeo software projects support Python. However, a global abstraction layer is lacking which would help to do "OSGeo Python programming". We think of well documented bindings to the various software projects which are handled as plugins (or whatever appropriate).

I'm going to write more on this topic in the near future, but let me begin simply by warning that those who do not learn from the history of PCL are doomed to repeat it.
