There is mmm-mode, but I don't know how well it works. I've heard it
has trouble cooperating with cc-mode.
Another option is to write a function that uses `make-indirect-buffer'
coupled with `narrow-to-region' and put that buffer in some different
mode. The package multi-mode.el uses this approach I think.
