Sure, I should have clarified what I mean. Responsiveness in remote environments should be like in a physical office. If you need to, you can walk up to someone and talk to them. Sometimes they're on a break, sometimes they left early, sometimes they didn't come in that day, no problem.

Generally though, you can count on being able to talk to someone when you walk up to their station. When running a remote team, I want people to generally "be around". We work very closely together though, so maybe our needs are not a good example.
