Socket protocol specification for transferring keystrokes?

Is there an existing socket protocol for defining how a way to transfer keystroke da开发者_开发技巧ta across machines? I want to be able to type on one machine and have what I type there show up on another machine.

For instance, the protocol might the field (eg. that the data is for a keystroke), data type (keystroke), and a value (keystroke value).

One thing that you could do is look into messaging. I am not sure if this will help you that much but, there are a lot of different implementations of this but a good place to start is looking at the JMS API.
