Send method should send the Message over specified Channel. Channel argument should hold ID of the channel where message is sent - not the Index in the Channels collection!!! This is because Index is different than channel ID - index can change, and ID can not.

When you implement your own transport, you will decide how you will actually transfer the message on the remote side. As far as wodBeep is concerned, message will leave the peer *whenever*, and remote side will get MessageReceived notification when message arrives.
