I have written a basic Perl web application I named Open SL Product Update Server for use as an external helper to product systems. It is completely open source, "free" software, released under the Gnu GPL (version 3).
the application stores basic customer, product, and product request information in an SQL database, acting as a queue for in-world delivery servers to service requests. Instructions for installation and use (e.g. specification of the web API that LSL scripts can use) are included in the download.
At this point the application is in an early beta stage. I have not had it setup on a web server and contacted it from SL, but I have tested the functionality briefly from the command line using Perl's debug features. The application IS similar to other web applications I have built in the past, so I don't expect any major problems, but there always might be little bugs here and there. So if you'd like to do the setup some place, push the buttons (so to speak), give it a test run, go for it. Or just peruse the source code for your own curiosity or edification for that matter. Any testing you do is appreciated, and please let me know here what issues you find if you do use it. I'll work on problems as I hear about them. Minus feedback, I'll do testing and enhancements over time, but I have a backload of other projects to deal with as well so progress might be slow.
Here's the link:

I originally developed this application as a response to this thread: /54/27/304671/1.html but I think it justifies its own thread for visibility and to reduce the noise in the other discussion.
Enjoy!
