How to stop a video hitting space bar?

Hi,

I am using a web streaming service that uses Flash to watch the videos. The problem I have is that I project those videos to people in a room, and I would like to use the space bar in the keyboard in order to stop the video, in case it is needed. Now the only thing I do is to push the "stop" button with the mouse, but that's a little bit distracting for the audience. Is there anything I could do, or something I can communicate to the developers to develop a system which stops the video after you press the spacebar? I would even accept a chunk of code to make it work. Maybe you have been in the same situation somehow.

Thank you!
