some more features

Here're some more features.

simple, yet powerful, config file syntax, including specifying gitweb/daemon access. You'll need this power if you manage lots of users+repos+combinations of access
apart from branch-name based restrictions, you can also restrict by file/dir name changed (i.e., output of git diff --name-only)
if your requirements are still too complex, you can split up the config file and delegate authority over parts of it
easy to specify gitweb owner, description and gitweb/daemon access
easy to sync gitweb (http) authorisation with gitolite's access config
comprehensive logging [aka: management does not think "blame" is just a synonym for "annotate" :-)]
"personal namespace" prefix for each dev
migration guide and simple converter for gitosis conf file
"exclude" (or "deny") rights at the branch/tag level
specify repos using patterns (patterns may include creator's name)
define powerful operations on the server side, even github-like forking
