I can vouch that it's possible to work. My wife has made many video links with family home in Texas, best way to 'see' everybody, everything and keep up with current events.
We'd done that first in front a remote camera, then the built in notebook camera for sometime, now with the ipad it's all the better with being able to switch the camera from the screen, (we see us and who we're contacting) or to the back lens, it makes it easy to see what we're filming .. even myself turning, which the wife did, sent from the shop in the back of the garden, the modem has to be 50yds or more away at the front of the house, no down time/delay at all.
The other advantage with an ipad, with an adapter lead you can connect HDMI straight to a TV ... now that's scary seeing oneself on a larger screen.
For all the technology today ... the end will always be we'll want to see the best (if only as entertainment) and have personal interaction with any demonstration as long as we have the demonstrators, should they, or the club want to video the event, that's down to the individuals involved.
Cheers David
