Here's my question, actually.
Would people be okay with using spout again? We don't have to have any fancy spout-specific plugins, but it did a fantastic job of making the server more efficient.
If you connected with a spout client while the server was running spout, your resource usage was little to none. It was pretty great because latency, block lag, and the server in general responded faster.
Yet, if you connected with a normal client, you used the same resources that vanilla minecraft did.
I personally really want to force spout again, but I know a lot of people were against it.
