A good exercise was a class on the Mpls campus about a year ago in which we set up web conferences in the labs and were able to 'play' with the tools. I'd suggest this may be a good way for teams to get themselves acquainted with the option some day. We were paired up and then each of us put in separate labs so we were technically in different sites.
We were able to pass around the presenter role, modify the screen and work on screens together. We learned the hazards in the class of opening up the entire group as presenter and how chaos could ensue!
I like the options available for redesigning the look of the screen. Some situations just call for a different look and options available to the audience.
Our dairy team has conducted a couple team conferences via UMConnect. Some are not comfortable with it yet and it suspect it is because they can't insert their opinions as readily as they can on a conference call in person. Having to raise your hand isn't all bad!!
