At Google I/O this week, the Silicon Valley giant showed off a vision of what web conferencing might be like in the future.

That got me wondering what actual web conferencing vendors are doing to make my experience a little bit better in the months ahead. We discuss with Info-Tech analyst Thomas Randall.
