Connections are P2P for small meetings (<=4) but switches in an MCU automatically when more people 'enter the room'. Still, if you're on the same subnet (in the same building) with some of the participants it keeps those connections P2P based on ping time.

We're distributed across 5 states and 3 countries. Everybody has an equal footing in the meetings since we're all on-line. Even people in the same office (we have several small offices) attend using Sococo - I can see other attendees in the background of some people's videos :)
