Something like this is planned for gimp 2.0.

There is certainly no clean way to do this. I'll stop slightly short of
saying that it is impossible, since bigger kludges have been done with the
plugin system, but it would involve lots of nastiness. For instance, if
you wanted to show what the composited image currently looks like, you
would probably have to copy all of gimp's compositing code and rework it
significantly to make it work in pluginspace. And it wouldn't show up in
the layers and channels dialog, etc. Sheer ugliness.

Of course, patches are always welcome. ;)

Probably your best bet is to check out the gegl module from cvs -- it
contains what will likely be the backbone of gimp 2.0, and might meet
