Not sure I understand the question, are you blocking for the data to come down the network before rendering the next frame? For game programming I've always used select with non-blocking sockets to receive data - and kept the transmissions to UDP to save time (obviously you have to expect some data to be lost). Wire time is always going to have too much latency for a message to be happily passed within the time it takes to render a frame. For syncing time I use a really simple algorithm - both machines send each other their local [game] time every few seconds, and if the received time is ahead of the local time then the receiving machine updates it's time to match - that way they are always out by at most the shortest time it takes for a packet to travel from one to the other.
