Assuming there is a panel in it, the feeder does not. That being said ... In my area the AHJ determination was that it is treated like an unfinished basement. His logic was that since the receps in the shed will have grade level access for yard tools (used ouside) treat them as if they were outside.
If you're only taking one circuit to it and the plan is to feed it GFCI protected (from the house), either a GFCI breaker or GFCI recep will do the trick. (recep is a lot cheaper)

See 210.8 2005 /2008 NEC

20-ampere receptacles installed in the locations specified in
(1) through (8) shall have ground-fault circuit-interrupter
protection for personnel.
(1) Bathrooms
(2) Garages, and also accessory buildings that have a floor
located at or below grade level not intended as habitable
rooms and limited to storage areas, work areas,
and areas of similar use
(3) Outdoors
Exception to (3): Receptacles that are not readily accessible
and are supplied by a dedicated branch circuit for
electric snow-melting or deicing equipment shall be permitted
to be installed in accordance with 426.28.
(4) Crawl spaces — at or below grade level
(5) Unfinished basements — for purposes of this section,
unfinished basements are defined as portions or areas of
the basement not intended as habitable rooms and limited
to storage areas, work areas, and the like
Exception to (5): A receptacle supplying only a permanently
installed fire alarm or burglar alarm system shall
not be required to have ground-fault circuit-interrupter
protection.
FPN: See 760.41(B) and 760.121(B) for power supply

Receptacles installed under the exception to

That was a copy & paste from the 2008 NEC.

There is no Panel/Sub-panel in the shed, just a single 12/2 with ground going out to the shed as a feed.

Thanks, what i am going to do is on the feed in, i will add an inline GFI switch (the kind with only the buttons, no outlets)(like this: http://www.alibaba.com/product-free/104072404/2006_UL_listed_GFCI_ground_fault/showimage.html )

Interesting link...
Pic is a faceless (deadfront) GFI; text reads 'receptacle.
Side pics are GFI receptacles. $3.xx(US) ea, 3000 pc minimum.
Interesting?

My take on sheds is that in most cases they are not permanent structures. Sure they might never move once installed, but they might.

I consider them a plug-in appliance. I pipe to a bell box on a post near the shed with a GFI receptacle and a bubble cover installed. Set up the shed with a WP pigtail and plug it in.
