Actually, there's one (that I know of, at least): Reindeer Optipix 3 (). It's a set of plug-ins, some of which are designed to do what you want: Blend Exposures will take the current image and blend it with the one you would have previously set using Setup 2nd Image, to obtain another one with increased dynamic range. Then there are several buffering functions to add a series of identically exposed images and stack them through simple averaging; the result will be an image with reduced noise, provided the series of images were really different takes of the same scene, and a tripod was used.
If you hadn't the luxury of a tripod, or if the images were misaligned due to any other reason, there's another function to align images using one of them as reference. This function provides you with sub-pixel alignment and several blending modes (one of them being "Difference", just like the one in Photoshop) to help you visualize the correct realignment. But this function is not as advanced as the one in Photomatix: it has neither automatic alignment, nor control points or rotation. In other words, it might be pretty much as good for realigning scanned images, where only X,Y displacement is to be expected, but it's no good for hand-held series of photos.
There are other functions in this plug-in set, most of them related to either sharpening, noise, or blurring. They're kind of... useful, but not terribly innovative.

Might be wrong but I believe Colin is asking if there is a plugin that will allow us to stack many (dozens or even hundreds) images to create one high detail less noisy image. There are a couple of decent stand alone programs available, 'RegiStax' & 'AstroStack', but it would be nice if we could do this in Photoshop.
An example(s) of stacking astro images is here;
