We have a web application (php) that retrieves audio via a local ip using flash (path to file gotten from mySQL). This is ok, but we can't access the files unless we're on the local network (clearly). Now we also need to set up a similar solution in a remote office which obviously our current set up won't work.
The main goal is to be able to navigate to our hosted (Rackspace) web application, and have it be able to communicate with audio servers in 2 remote locations (here and the remote office).
We're looking at VPN (OpenVPN) solutions but they seem complicated and potentially overkill (although very secure). How can we securely access audio from our web app and be able to stream it with flash? Any detail information I can provide. Just not sure what kind of info is needed.
