s (RPC) on the server-side and the server can call methods on specific clients. A SharedObject can be used to synchronize complicated data structures and call remote methods on multiple clients in one go by having clients subscribe to a shared object. Standard ActionScript objects are transported across the NetConnection using the Action Message Format (AMF) which is handled transparently by the server and flash client. The server also allows users to receive and publish net streams. When viewing a net stream the user can either create their own to view a remotely stored Flash Video

(FLV) or the server can instantiate a net stream and play a video on it, the latter method means that every user will be at the same point in the video when they subscribe to it as they are all viewing the same stream.
