Video conferencing is something that may be helpful in promoting your book or other services you may provide. Like many, I have virtually attended conferences that I view on my computer screen, and I have been on teleconference phone calls. Attending a video conference is popular, but only on futuristic movies have I seen meetings where the attendees who can’t be physically present can be viewed life-size on screens in the conference room.  Telepresence makes this a reality, stop by and see if this HD Video Teleconference technology at lifesize.com might be helpful to you in promoting your book, business or service.
