Access control: the ability to constrain developers to operating in specific areas of the tree, implement branch-based policy restrictions, as well as to enforce policy such as tagging of commits for developers working outside their normal areas. Implementing these via hooks would not be a regression from what we currently do in CVS.

Partially Supported

Currently hooks can be used to restrict many premissions in [“Monotone”], but a fully featured ACL system is in the works and will be available “soon”.
