Here's a simple, but important tip, when delivering Remote Demos to an audience of mulitple people in one location: Ask your host or Champion to move the mouse on the "participant's" (audience) computer out of the way!
I recently watched a number of Remote Demos presented where the mouse on the "participant" machine was left in the middle of the screen. A number audience members were confused by this, since they weren't sure which mouse cursor to watch. Solution? Have a team member (if present) or a Champion (or someone else at the customer site) move their mouse out of the way - for example, to the bottom-right corner of the screen - once the remote session has started.
