Anyone here use Open Source Software?

I have been looking for a tool, preferably written in PHP+MySQL, that I can use to catalog my various possessions. I have seen some online sites that provide some of the functionality I am looking for, but I won't share this type of information with the world so I have to host the solution on my own Linux server or within a fat client application running on Windows, Mac OS X or Linux (preferably all.)I have considerable DVD and book libraries and a few hundred CDs plus photos, computers, ham radios and other electronics. If something unfortunate was to happen to my home, I wouldn't ever be able to enumerate them accurately and wouldn't get fairly compensated by my insurance company.Unfortunately, my search has not resulted in anything simple to use that stores the information in a format that's easy to generate a report from (ex: print a report as PDF and ship it off to a remote relative in case something were to happen...)In the interim, I am going to take a bunch of digital photos of my junk and store them offsite until I have a better solution. Ideally, the solution will provide the ability for me to check items in and out when loaned to friends.Anyone here using anything like this?Thanks!WB7SGL - Rob
