Video conferencing is a type of groupware that allows interactive communication from different locations linked together using telecommunication technologies and video. It's a great way to bring people together in a conference setting without having to rely on all participants being in the same city at the same time.

Small business users shouldn't underestimate the flexibility of more domestic solutions. Often referred to as video calling rather video conferencing, services such as Skype, which has a full multi-user video dial-in, could be a great way to get started with video conferencing. iChat for the Mac is another quick, low-tech approach to communication.
