At my day job, I (somewhat to my shock/joy) appear to be implementing a JSR168 (ie, java portlet) container. I probably
won't do the whole spec – we need it so we can deploy portlets on it until there are better options, but I do aim to get
it as complete as possible.

Believe it or not, I'm pretty sure I'm going to be able to do the whole thing inside a servlet. Has anyone else done
this? Any tips or pointers?

If only Pluto was in a useful state…
