Robin Good: If you are looking for a free video conferencing solution, here is my selection of the top 15 (and more) solutions available right now online.
I have personally checked each one of them, and while you may not like each one, they all guarantee the ability to video conference with more than two people (FlashMeeting is the only exception I have included) without you needing to pay anything for it.
Some, as good as Vidyo or Zoom.us may provide HD quality video and even full support for mobile platforms. Others, like MeBeam or Sinfor offer bare-bone ad-supported solutions that have zero frills but can do the job if you need an immediate, zero-cost solution.

P.S.: Feel free to suggest tools you know that should belong in this collection.

There is no limit to the number of participants you can invite as, MightyMeeting effectively downoads your presentation to each participant and then synchronizes your moves within it.
The host can decide whether video-conferencing is active or not, and whether other participants can contribute and upload their own files.
MIghtyMeeting presentations can be seen across all kind of devices, screen sizes and operating systems without issues.
A handy "portfolio" function allows the presenter to see all of the slides available next to the one being displayed.
*Videoconferencing, powered by WebRTC technology, works only with the latest versions of Chrome and Firefox.
My comment: Ready to use after 30 seconds of browsing. Super-easy, requires no downloads or plugins and works across all devices. A very handy collaboration tool.
Not recommended when presenting very large files and having other participants on a slow connection. On the desktop, if you use it in full screen, remember that you need to "swipe" with your mouse to move inside your presentation..
Free to use.
