If we used steganography on this image and sent variations back and forth across the world, the NSA data center would end up having a section devoted to steganographied pictures of itself...

And then we could use steganography on the images that had already been steganographied...
Yes! Do like!

Some of the steganography packages also encode audio too...
So we could hide this picture in a song that truly is annoying and alter it to hide the key for the message in the song.. Say 99 bottles of beer on the wall. Every modified version would have the key spelled out in the song by rearranging the song so it's out of order and the order unlocks the message.
Of course there would have to be false positives in the arraignment...

I like the way you think!
This might be gilding the lily, however, since the NSA seem to be masters of creating false positives themselves.

So order of operations...
- all the verses in the song split by verses
- the exact point of the split is semi random
- input key to custom 99 script
- script re-arrainges file
- glitch effects and mp3 stutters strewn about
- actual message encoded into newly modified file
voila, PITA file to decode.
Of course they can / will automate the decoding of this if it became popular but it would gobble resources.

You're on to something here. This one might do it: http://www.youtube.com/watch?v=dQw4w9WgXcQ

Rickrolling the NSA, in such a way they felt compelled to examine each and every one in detail?

The NSA says they have the capacity to record pretty much every conversation that crosses the ocean, and this picture proves they have invested in plenty of space for the hard drives to do so.
Why anyone would believe that they are limiting themselves to a small number of targets defies common sense.

How about "The Rainbow Belongs to God?" Thousands of copies, almost but not quite identical, so the hashes come up different.

Have to vary the length as well. Just chopping it up into a few chunks and concatenating a random number of them should be adequate.

Kinda' wish this was all a cover...

Where do they back up the data kept in this one? There must be another NSA data-center someplace else.

First rule in government spending: why build one when you can have two at twice the price? Only, this one can be kept secret. Controlled by Americans, built by the Japanese subcontractors. Who, also, happen to be recently acquired, wholly-owned subsidiaries...
.. of Hayden Industries.

Looks like the power lines going into it are pretty exposed. But, I guess they have generators powered by whatever is in those tanks on the right.
