Would like to add a private message command - this should be relatively simple, however, it will require username for each user to prevent multiple messages/hosts getting the same message

Currently, the client names are the client IPv4 addresses. I would like to change this to force a user to connect with a screen name.

Would like to implement session-based RSA encryption utilizing a different, randomly generated RSA keypair for each client.

Would like to allow the server to load a configuration file, or create a default configuration file if one is not present.

This would set future user caps, MOTD files, connection rules, etc.

Adding an optional message of the day from a file would be nice, and should be very easy to implement

ScrollPane has no autoscroll, and should be fixed to allow pane to autoscroll when the vertical scroll bar is at the bottom.

Would like to, in the future, implement an optional user cap for the server

Currently, messages are received from the client and sent to the client using an RSA asymmetric key encryption scheme. Along with its slow speeds, it only allows us to encrypt a small message (in our case, 245 bytes).

This both limits the execution speed of the server and the overall length of the message.

The way to fix this will be to implement at least an AES-128 bit symmetric encryption scheme which will send the key via RSA from server-to-client, although more preferable would be AES-256. I'd only have to bump up the RSA key size, which would incur the cost of a two-fold amount of key data being transferred in every packet.
