Hello:

Where (what) is the canonical site (or book) for PF.

Are there any site where talk about PF is a application (like for OS X).


One Last, has anyone done any work on using CARP, I know 
synchronizations depends
on similar cpus with similar clocks and constrained  clock drift. Just 
wonder.
