doh :D sorry for the stupid question ;) I just realized what I had

Hmm so many cool stuff in one framework :)

Currently I'm doing some project and using PEAK, but because I need to
have it done ASAP i am using CherryPy instead of peak.web. It's not
integrated like peak.web is (for obvious reasons) but it's very nice
to be used with it nonetheless. CherryPy provides a way for me to
publish my "location"s which reflect to Peak components. So as you can
imagine one almost thinks the two frameworks were written in a joined
effort ;)

I don't know if there is interest for me to share this experience to
be in the wiki. I have used peak.security as well and written some
code to integrate the two (Peak and CherryPy).
