I realize that this is a subjective question, so I've marked it as a community wiki. I think that it is pretty specific to programming teams, though, so I've posted it here as opposed to somewhere else.

I'm leading a small game development team (four people) as a side project. We are a disjoint team, with everyone in different places, but we do have some of the mainstays of an organized team.

1. Source Control
2. Continuous Integration
3. Bug Tracking
4. Document Workspace
5. Regular Meetings
6. Calendar / Schedule

How do you keep your small, disjoint teams on-track? I tend to agree with Joel's opinion about when and how to micromanage and know that my team is motivated, but it can be easy to fall off-course when everyone isn't connected in a physical way and doesn't see what other people on the team are doing. Suggestions, feedback, or criticisms are welcome!

Edit: I'm managing the team; I'm not looking for automated tools or anything to do my job for me, just ideas for approach or process that might help everyone feel more "connected" and involved.
