I think this is an unnecessary over reaction. You're confusing an acknowledgement when someone knocks (basic human communication) and being interrupted all the time.
Acknowledging communication can also be: "I'll be with you in 20 minutes". That gives me the option to (in 95% percent of the cases) respond with "cool" and plan my own time accordingly, and in 5% of the cases to respond with "sorry, we really need to deal with this now, and here's why".
How fast you respond when someone tries to communicate with you has very little to do with remote/local. I love remote environments, they have huge upsides. Not being able to go to real time when necessary though is a major problem.
