Culture transmits largely by physical proximity. Osmosis if you will.

Culture transmits by communication, and nothing else. If you don't have a good (or equal) communication with your remotes, things are going to suck.

If you have a good communication with your remotes, they'll absorb culture faster than the most introvert people that are in the actual office.

Your post essentially lacks any base for the claims you make.

I think this is better served by saying that culture transmits by communication, in all it's forms, which include body language, physicality, etc.
