[development] sandbox, project nodes, release nodes, and drupal.org's contrib CVS repo

derek, i couldn't agree more with everything you've laid out -- this makes a lot of sense. the only thing i would add (and i think you kind of already covered this) is: no matter how much structure you build, there are exceptions, and chaos. so let's get a more clear policy in place that encompasses all the new tools we have (so that development that would benefit from the model you laid out can take place in a more informed manner) and also have a community place to put 'other stuff'! :)
