I want to start a new project.
The project is a web-based media center built in web2py.
Playback will done on the machine hosting the application (hereafter referred to as the HTPC). It is not intended to be used for websites that stream all your media. The HTPC hosts the web-server on the local network. Any device on the network with a web browser should be able to control the HTPC through the web application, including the HTPC itself, or any smart phone or tablet.
By default, there should be a core set of features for basic functionality. The application also needs to be extensible, using components and plugins.
Arch is obviously going to be the target OS, since this would be best used with standalone WM setups where a web-browser is launched on the HTPC with a homepage set to the web application. With that said, there's no reason why it shouldn't work with other distributions.
Let me know if you are interested. I have spent some time on a similar personal project myself, but I wanted to start over, making it a community project from the beginning.
