Given the overwhelming number of areas that POE extends into, you might want to point him to an area that is specific to his needs.

Not being familiar with POE myself, I went and looked around. Rob, these POE links might be helpful to you:

• Evolution of a POE server - Looks like a good introduction to POE itself while building a fairly complex server.
• POE Cookbook - Lots of little, well commented POE implementations
• POE Whitepaper - introduction in PDF form

Hope these help,
