A generally accessible web page has some advantages--it is easy to  
read, and usable even if you don't have the most recent version of  
the software, for instance.  It has some problems too.

The biggest problem is that the registry is not maintained or found  
within the source code: you have to look elsewhere to get the current  
state, even when you are working in the code, and you also have to go  
someplace else to edit it. Another is that our web site is sadly not  
in shape to be a good tool: using a wiki is always a bit annoying,  
and especially so at zope.org these days.

I propose that we actually store the registry in the Zope code,  
probably in the package that defines the 'condition' attribute.  We  
even get a bit of web presence, thanks to svn.zope.org, for free.

A point that lands in either camp, depending on your position, is  
that the wiki only requires site membership to edit, while the  
repository approach gates it to contributers.

For what it's worth, I'd further say other shared 'virtual registry'  
type uses that spring up should use a similar pattern.
