I've submitted my Draft #1 of the eventhandling for RUNEmulator to an RSPS community and have gotten some great feedback on how to improve it. I now intend to do some editing to Draft #2 and release Draft #2 to the community to get some final (hopefully final!) feedback on the eventhandling system used in RUNEmulator. I can't give you a timeframe on this: I'm prioritizing work on networking right now. I'm sure I'll get it done soon, though.
A working Netty networking implementation (in Java, of course) has been added and I am now constructing an idea of how I'm going to organize client request handling. I'm most likely going to use a majority of something a peer created (full credits to him!) and just customize it to fit with RUNEmulator appropriately. The impl he has is stellar!
