online searchable exploit code database?

Evening everyone, sorry for the late mailing :)

I was asked if there is 3 things online.
1. a searchable database of exploit code with detailed descriptions  
on what it does with vendor link etc. I couldn't find any, at least  
not any free ones. I think he is looking for something like a  
wikipedia of exploit code.
2. a blogging community for security professionals. kind of like  
myspace or blogger.com but specialized for security professionals  
( even a blog directory would be a good start already I think)
3. a collection of security publications in various formats (like  
SANS reading room but where anyone can submit a paper for free.)

The reason i was given to research this was that there is apparently  
interest of providing one of these or even all services if there was  
enough if any demand.

If anyone can give me some links or insight knowledge I would  
appreciate it since I coulnt find anything really substantial.
You dont have to mail the whole list , you can contact me offline.

Thanks already for your time.
