Hadn't thought of the namespace situation. CPAN does have control  
over what namespace perl modules can take, at least at a top level.  
Not sure how this would work for plugins, which is just a single file  
name... Any ideas on controlling this? Or is it even a problem?

I like CPAN's rating system. It is not fully used, but it gives a  
good general feedback on the quality of a perl module from the users.  
I'll add to my wish list.

As for quality, I was thinking that there are varying levels of  
"certification" for a plugin (this is based on an email thread a long  
time ago, which I can't recall which). I propose that the dev guide  
should show level 1 as "returns 0 OK, 1 warn, 2 crit, with one line  
output", --help/-h with output, --version/-v for version info. Level  
2 is perf data. Level 3 is stuff like -v -v -v for extra debug  
options and internationalization. Level 4 is stuff to do with  
integration into core (using common libraries, etc).

With some work on the new test harness, I think we could probably  
create a generic test harness which proves which certification level  
a plugin is at.

I'm trying to work out our requirements for the NP collection system.  
Then I plan on having a discussion with Nagiosexchange, where I'll  
find out if they can meet all the requirements we have, in return for  
us officially promoting the use of their site. Seems like a win-win:  
we'll get what we want, while they gain exposure.

It could be that we decide to keep it in house and develop our own  
collection system, which is valid (for instance, control of namespace  
could be a major issue). But then I really need commitment that we  
can do this ourselves!
