Syncing Offices across the Pond

One of the main conclussions of Zemanta gathering that took place last week, was that Skype calls that we do every Monday in attempt to sync both offices just aren't working for us. The quality of video and audio provided by Skype, GotoMeeting, and a few other teleconferencing solutions that we have tried is simply inadequate for efficient communication, and maybe even the format of the calls is inadequate. Therefore, I'm reaching out to you for advice how should we do syncing of our New York and Ljubljana offices so that people would feel at least partially as close as we felt last week with everybody being present in the same place.
