The issue is that in person you constantly have informal "meetings" where information is shared and impossible to record, unless you force everyone to walk around with sound recorders on. Which come to think of it is something that might well be done in some companies I've worked for before.

Trivial, it's a problem that's been solved for a while and I managed to get it working in a couple of days of messing about.
I'm positive that people working remotely can just as easily have informal meetings were they won't be recorded. In fact, I'm absolutely sure that a good segment of the workforce will make sure they have meetings in that informal sense, specifically so the recordings aren't happening.
