Linux users were unable to enjoy, popular on-demand internet multimedia streaming service Netflix as it requires Microsoft Silverlight plugin, and the Mono-based 'Moonlight' implementation of Silverlight for Linux does not support the "Silverlight v 5 DRM".
With true spirit of Linux geekry, the developers of project "Pipelight" spun a Netscape plugin hack which allows Linux users to run windows only plugins inside any Netscape Plugin compatible web-browsers. Currently they have got Silverlight working with its core features like watching DRM protected videos.
