Cool - let me know if there's something I can help with there. I had it in mind that it was
still a work in progress.

Things I broke with changes to the repository API :)

I'm using them, so I can help make sure they still work at least for the next release.

Great - was going to suggest both those things.

Agree these are all good things. I like the Jetty one, but having a few different distributions
(including slim ones with less functionality) has long been a goal of mine.

I like the look of vaadin (still haven't used it in anger though) - the concern I heard raised
from Emmanuel was that it was network heavy.

This might be something good to just start doing and have some bits dynamic and lots of legacy,
then gradually break it up...

Agree, or at least make Redback a wrapper around Shiro so it's a lot smaller. Back to that
list you mentioned before, if we can let go of some features it might get easier.
