Slappybox is a program you can run on your computer that turns your PC into your own video sharing website. With Slappybox, you can add your videos to your new site, and share them with your friends, relatives, co-workers, or even complete strangers across the Internet. The only thing your visitors need to access your Slappybox site and play videos is a compatible web browser (see below for specifics). They just type in your ip address into the address bar (or domain name, if you have one), and browse your Slappybox site like any other video sharing site.
The second Slappybox beta is now available. This build includes networking support, allowing you to link up multiple Slappybox installations to create a single searchable media catalog.
