[Boost-users] Boost::Asio help for viewer

I am designing a viewer that communicates via the network some actions, like playback, scrubbing, etc. I decided to code it with boost::asio, but I am too unfamiliar with it and the examples did not help much. What I need is the following: - server starts a group - one client connects to server - server and client do several handshake transmissions to sync (same movie file, etc). - client or server perform a playback or a seek to certain frame and the other (client or server) follows. Can someone suggest what should I use and what steps to take in draft form? Currently I have two threads one for the server and one for the client but lack knowledge of the asio api on how to perform a handshake (a send/receive pair, basically).
