Remotingly starting a sound file

[viajador]

Hi there!

I'm trying to find out how to do the following:

- build a flash program that plays a sound file in a given computer (the server);
- build an interface (on a webpage) that allows the user to control that program, starting the sound file on the server.

Basically, I want that someone, on the web, to be able to play a sound file on another computer.

How can I do this? Must I use Web Services?

Thanks in advance,
Leandro
