Shameless plug here:

  read chapter 4 of my thesis "Programming Techniques"
  and  chapter 6 "Building an application"

  Chapter 4 shows how to "abstract out" concurrency - so you can write
concurrent things (like client server models) with sequential plug-in code.

  Section 6.1.1 "How behaviours are written" goes into detail of the callback
style of programming that is the basis for all behaviours.

  Once you've understood the basic idea you should find it easy to roll
your own "custom" behaviours.

  The thesis is on-line at
