I'm very much interested in keeping Nevow alive, it's a the center of 
quite a few
projects of mine.

Definitely, Livepage is my bread and butter, although a rework of the 
Livepage part
  might be be beneficial, I just never found the time to do it and the 
code just flawlessly
does what it advertises.

I have no association to the name but ripping Nevow apart and still name 
it Nevow would be
at least misleading.
