You might make everyone on an even footing; but the people around the table would have been more effective around the table than in their separate cubes with a headset.
At work we don't use Sococo but instead rely on Skype, Google Hangouts or Lync (depending on the project/client), but our experiences have matched what JoeAltmaier has said so far.
Whenever possible we prefer everyone be connected individually as opposed to sitting together in a conference room. The conference room becomes a distraction, impedes proper communication between all members and the attention spans increased when everyone connects from their workstation. The conference room creates two areas with two distinct conversations so if we're really aiming for an integrated environment we enforce people connecting from their workstations as opposed to using a conference room.
Culturally it also spreads that idea that those sitting together are better than the remote workers, which given our line of work is an unproductive idea to keep propagating. And while there might be differences, they pale in comparison to the negative impact that ignoring or discriminating remote workers has in our projects.
Deny! That's exactly what I'm getting at. With a good thorough always-on collaboration tool, you can actually share better and easier than crowded around a table trying to share a document, or fool with a projector, or waiting for somebody to arrive, or a hundred other time-wasting things that happen in physical conference rooms.
