I would like to compliment the author on the quality and ease of use of the sockets plugin and the open source java server.
Once I had learned how and why everything worked, making use of it in our project proved as straightforward as I had hoped. Of the several Marketplace purchases that we have made, this has been by far the one with the least complications and the most gentle learning curve. This single plugin has likely saved us months of development time.
It is perfect for multiplayer data handling and I have no doubts but that it will prove equally useful for practically all of our other external communication needs.
