Hi Ben,
I'm sorry that you're having trouble learning how to use actionlib. I just put together a fairly short example of how to use the simple action client callbacks:
http://www.ros.org/wiki/actionlib_tutorials/Tutorials/Writing%20a%20Callback%20Based%20Simple%20Action%20Client
Hopefully this will give you something to build off of. If it doesn't answer your questions, please let me know, and I can try iterating on the example.
Good luck,
Vijay
There are some examples in the linux_networking stack. They are still
under heavy development, and not particularly simple, but should give
you the general idea.
C++

Python
