1. In Composite mode add an Input Texture Node.
2. Create a Material for default object, set it to Noise, set Texture Node value to this new Material.
3. Add Distortion Scale Node and set it to 4 for x and y.
4. Add Color Mix Node, set it to Multiply and fac of .3.
5. Route Render layer to Multiply Node image (top) and image out to Composite.
6. Route Texture Node to Scale Node, and image out to Multiply Node (bottom).
7. Save project, same as one attached, and render it.
Bug: In 2.63.0 you will not that the size of the Noise is larger then in 2.63.22.
in 2.63.22 the effect is not as intended, size is too small, this is based on a project started in 2.5, with same settings, so unless this was done to fix something in prior versions, I would say something has changed; it may be that the Scale Node is not functioning correctly, changing it from 4 to 8 does not seem to have an effect; so its possible that the Texture Node has nothing to do with it, but its how I noticed it, and did not find a bug report similar to this one.
Tried this on 3 machines with different Linux OS's
Currently running 2.63.22 in Arch Linux x64 and 2.63.0 in LMDE x64

Hi!
I can understand that you think that it is a bug, but in fact the scale node is not pixel based anymore (and this is the effect you want to simulate). The "Noise" texture is implemented in such way that it can only do pixel based algorithms.
Options:
1. Do not use Noise, but distorted noise as it has not the pixel based limitation.
2. Add a blur node between the texture node and the scale node (set blur to 0 so it doesn't blur at all).
3. Enhance the Texture node that it will buffer the noise texture (IMO not a good option as it also reduces a lot of the new functionality)
I hope this will help
