What is "the file method"?  How do I treat GPIO connections as file 
paths?  Somewhere in /proc?

Earlier you wrote:

    Look at the comments in the library it self for how to solve
    the Accessing the GPIO (of a raspberry pi) without "sudo" problem.

The stack script isn't very big, and perhaps I'm just pre-coffee but I 
couldn't find anything there about sudo.

Where should I be looking?

I would imagine so, but in Python it's easy because someone wrote a 
component for GPIO.  I haven't looked into this deeply so forgive my 
ignorance, but how does GPIO present itself to an application?  A sort 
of named pipe, or serial I/O, or....?
