version control

This is a long post, grab a cup of tea... (or better still a beer)

I manage a small team (currently 3 soon 5) of grographically distributed developers developing and maintaining a few (currently 4) projects in different stages of the lifecycle. I am familiar with managing teams developing web applications but up until now my Drupal experience has been largely solo. Developing large Drupal projects and working in a team is relatively new to all the other devs so I see this as an opportunity to encourage a sound development process using the appropriate tools.

Thank you Adrian for a great presentation at Drupalcon today! Since we didn't have time for questions I'd like to ask you quickly about something that I kept thinking about during your talk:

How does this fit into a workflow like mine where I develop and maintain sites using a SVN repository? I usually do both development and upgrading of my sites locally and then commit the changes before going to my staging or live sites and update them with SVN. Do dev or staging servers have a place in Aegir? How do you do it?
