Some ideas for new software that I might or might not have time to write:
handgrenade, a fast duplicate-file-deleter that has client-server capabilities
mysql-process-tools, a bunch of tools for dealing with mysql processes (monitoring, killing, etc) that are geared for multi-server environments
django-skel, a tool that lets you create a skeleton django project and initialize it as a new project; should be able to load from directory or revision control
chapman, a 'backup script toolkit' that allows you to write backup scripts at a high level in python; probably based at a low level on rsync
