Share data between 2 local flash applications and use dynamically

Hi all, I'm assuming what I want to achieve is possible, but not entirely sure on how to achieve it.

I work in a theatre and I'm looking to create a seat map that can be shown to members of the public as they book their seats, so they can see where they are going to be sitting. The main problem I've come up against is that the person viewing the application, will not be using it. I need the Box Office clerk to be able to input data, and then the seating plan shows the seats on a second monitor (public facing)

What I thought of doing was to create 2 flash applications and used Shared Objects to pass data from one to the other. In the Clerk application, they would input the seats that are being requested and click Submit (or whatever). In the Public application, these seats would then be highlighted. Ideally, another dynamic image would change to show the view from that general area of seating.

This doesn't need to deal with availability in any way, I just need to be able to show people what seats they would be sitting in.

Any help or advice would be greatly appreciated, or even better, an easier way to do it!

Cheers,

David
