I would like the option to run the presentations from your server rather than one (or more) of he remote machines. You already have cloud infrastructure (for example you host my recorded webinars for playback) and you are logmein ... why not allow the presentation to be run from a central hub. The organizers, panelists and attendees will each be connected to the server with as robust connection as their location can provide. This should minimze the potential for problems when an organizer or panelist turns out to not have as reliable a connection as desired.
