Unfortunately I am currently too busy with document reading/reviewing at my
work and hadn't time to look at it. I hope that it goes in the right
direction.
To get more feedback on it it'll be fine if you could create a simple webapp
sample and add it to C2 with a brief description/documentation. IMO,
generally, people is too lazy to install it and try if they are not
interested or don't know what is it for.

Hope, I'll have time to look at it a little later (maybe on the next release
;) ).
(Btw, I am not from the core team)
