Now at the Python community's repository: http://cheeseshop.python.org/pypi/OWSLib/.
OWSLib 0.2.0 is the first release after switching from the GPL to the BSD license a month ago. The other changes involve extended (but not yet complete) service metadata introspection.
Update: here's a link to all GIS packages in the cheeseshop: http://cheeseshop.python.org/pypi?:action=browse&c=391
