I've been working on a new version of the vpwiki api (the api that lets VoodooPad talk to servers for it's data) with Michael Wilson. The current version has been bumped up to 0.5, and is available here: http://flyingmeat.com/vpwiki_api.html. I wrote a java interface for it, and ran javadoc against it to make the web page. Seems to work alright.
If anyone has any suggestions or ideas or comments or whatever- please let me know.
