Short Term

Revert privilege-dropping code; rely on whatever daemon wrappers are available to handle it instead
- Will make it more portable
Add pre-update, post-update hooks
Add service wrapper scripts for Debian, Red Hat
Add LICENSE file; remember to attribute Go for privilege-lookup code

Long Term

Consider using libgit2 to manipulate repositories
- PRO: easier Windows deployment?
- CON: external library dependency, and is Windows really that important?
Add configurable repository update strategies
- Fetch + detached HEAD
- Bare repository + working copy
- Vanilla git pull

Cool Ideas

Implement git commit hook that produces a valid push message
- Should probably read .git/config values for push destination
Add support for a heartbeat ping
Add support for stats monitoring?
