I use ControlPlane - http://www.controlplaneapp.com/ - which monitors your "context" (like location etc.) and lets you trigger events on context change.

Just added some rules so that Dropbox quits when I'm in my "mobile" context, but reopens when I am in my "home" or "office" contexts. Will see whether it works on my commute later.

Nice! Thanks for that tip.

And I'll note that after my commute home, I do seem to have a bit more battery life than usual. So that's a win.
