This means that by default the allmydata-tahoe egg will be a directory with a tree of files instead of a zip file containing files. I prefer the former because it makes it easier for people to hack into it.
Unfortunately the files therein are still going to be .pyc's instead of .py's, if I understand correctly. I would prefer for them to be .py's. See also discussion on the distutils-sig mailing list:
