Looking for this special software?

[perikillo]

Hi people.

I want to know, what came of software could help with this problem:

My boss need a software for the company, where everyone could put
reports(xls, word, pdf), change information, with user rights, put meetings,
and just with a browser everyone could access the company information.

I was reading a magazine and they where speaking about
www.centraldesktop.com, I read what we can do with that peace of software
and looks like is what I'm locking for.

Exist something similar in the opensource?

Or what software could help me?

Thanks for your time people!!!
