I am doing solo x last three years. I have a local doctor covering for me when I am on vacation. She is physically in my office half days. Otherwise she is doing H&P at psychiatric hospitals and is pretty flexible. I have VPN access and I am able to refill meds, check labs and answer messages remotely. It does not bother me. Two years ago I stuck in Europe during volcano disaster. I seriously considered seeing PTs via Skype - chronic things, refills, etc. I still could have billed based on face to face time. It would have been interesting to see how insurances would react because skype is face to face. But then skies opened (literally)and I flew back.
