well, after some weekend hacking, i have committed XML-RPC support to the postnuke CVS. unfortunately i had no time to finish it properly, so it will probably not work for now. its most likely a minor issue though, and maybe there is someone else interested in fixing it up. meanwhile over on bloggerdev, the discussion continues.. and some other open source projects might support this api in the future.
it will be interesting to wait for a little while and then cook up a great demo for the talk series i am preparing at zurich university..
