Hi Chris, Are we expected to implement UDP ACKs/NACKs, or do we assume that UDP packets will always arrive? It's never explicitly said if we have to, even though the project description does say that UDP is unreliable. Also, for the demo, do we have to show the servers communicating between different computers? On the project page it says "station servers will execute on one or more computers," but on the getting started page it says "Because our project runs on a single computer, all URLs refer to the hostname localhost." Obviously, if we're communicating between different computers, it would be necessary to have ACKs and NACKs, but I'm not sure if it's necessary for a localhost connection. Cheers
