Peter, Overall, I would say that writing an Apache authentication module is not a very complicated task (speaking in hindsight). I would estimate that a programmer with reasonable C/debugging skills would be able to write a similar, robust module in about 5-8 days time (dedicated), which allows for testing, debugging, etc. The first pass that Matt speaks of below is just that, a relatively stable, "functional" module that could interact with the CAS protocol.
The Apache API, like Matt says, is not the best documented API on the planet, but with use of resources like Google code search and access to the source code of existing Apache modules, it is not too difficult to find ways to solve problems you might encounter as you write the module. In the end, there are only so many hooks that Apache provides to handle authn/authz functions, and you just have to be sure that your intended solution is one that can be implemented in Apache using the hooks they provide.
