The ones that I have seen use Flash.
No disrespect meant, but in that you need to ask questions like that which you have, I am afraid you are well out of your depth doing this sort of thing, so the best advice I can offer is to get in touch with a local development shop and engage them to do the work.
As for what might already be out there... did you like use Google or something to have a look?
thanks for input. I did search on Google and otheers. no result found.
as far as having someone to do it, I seriously don't know anyone to know CF! most compnies work with PHP. unless I just take a chance to try someone I don't know.
I would appreciate more hints.
Assuming you do go with Flash, you could do the CF part and contract out the Flash part.
If you wish to buy instead, then my advice is as follows. Find a theater on the web that has an application similar to what you want. Call them and ask who built it.
