From ralph-heinkel.com:
While being at EuroPython in Florence the latest version of pyRserve has now been finished and is available via pypi (easy_install -U pyRserve). If you are at EuroPython, too, and want to talk about it just come and see me. pyRserve is a (pure python) client for connecting Python to an R process on a remote server via TCP-IP (using Rserve).
