I quickly looked at this.  I'm curious as to why you didn't choose  
POSIX as the abstraction layer for the "OS API" and "File System  
API".  I'm always having the argument with my clients (I know, not a  
good idea) that these sort of layers ARE what POSIX is defined for,  
and the client's home-grown wrapper to provide portability is a dumb  
idea.  I try to phrase it more gently. When a vendor implementation  
is deficient it's a bug, you work around it with -I wrappers and ugly  
redefines and report it as a bug to the vendor, without uglifying  
your own POSIX compliant code.

The "Hardware API" is IMO different since I'm not aware of anything  
comparable to POSIX.
