This weekend, I found out that the Preon repository wasn't available for anonymous access. That's just awful. In order to make sure everybody has access, I also started pushing to Github. That way, you can get the latest versions, if you need to. If you agree with me that this is suboptimal, please raise a vote here.
Update: the issue with the Codehaus repository has been fixed. I will continue pushing to both Github and Codehaus for a while, but the blessed repository is the one on Codehaus.
