I'm afraid that even a limited one can be quite a difficult task,
since it requires good knowledge not only njs internals but nginx too,
and involves async interaction between njs and nginx.

Anyway, if you're brave enough, then take a look at the existing njs
modules for nginx: http://hg.nginx.org/njs/file/tip/nginx
