Small Community File shareing software

I belong to a small community of about 500 to 1000 people. We are spread across the globe and would like a fileshareing system that allows us to share files with each other. Although we are all a part of limewire and kazza, it is at times very hard to find the 1 file we want in a system conataining millions of users.

Is there a p2p software that will allow us to have our own limeware in a sence and or can any one on th8is board be of any help in creating such a program?

Thank you for your help,,, please email Edit with your suggestions or reply on this message board.
