A brief update of things I've been working on:
Snakepit is a port of (part of) HiveDB to Python and SQLAlchemy. It will help you write database-backed applications that need to scale further than one database server, or even a master-slave setup, can take you. It's MIT licensed, that is, pretty much as free-for-all as it can be. And it's still work in progress, so don't be too harsh yet ;)
gitosis aims to make hosting git repos easier and safer. It manages multiple repositories under one user account, using SSH keys to identify users. End users do not need shell accounts on the server, they will talk to one shared account that will not let them run arbitrary commands. gitosis is licensed under the GPL.
First real release will come as soon as I have to time to go through a couple of really minor nits. It's been self-hosting for a long time now.
