I have uploaded the Queue manager Server and Client. In the programs current state its very simple, yet very reliable, in the next version I would like to experiment switching to a TCP protocol. With the protocol change I would like to add automatic detection of the queue server, showing the queue client how many other tills are in the queue and send a notification when the server directs a customer to their till.

If you find any bugs, problems or if would like to see a feature added please add them to the bug tracker.
