I was browsing some page in the Zope Community while following some 
links on SmallWiki page and I found that:

http://dev.zope.org/Wikis/DevSite/Projects/DeclarativeSecurity/FrontPage
http://dev.zope.org/Fishbowl/Introduction.html

which can illustrate how a project like better network or TTF could be 
settle and supported explicitly
