How To Sopcast on Ubuntu
Setting up Sopcast in linux can be bit of a pain. But recently, I stmbled across a very nice project called sopcast-player hosted in Google Code. This project offers a GUI based windowed player similar to the Windows version of Sopcast.
The authors are also kind enough to compile the project and give installable packages for various distributions.
Enough said, this is how you install Sopcast on Ubuntu.
Download the package sp-auth_3.0 from here
This package has the script that acts as the streaming server for the video.
Download the package sopcast-player from here
This package has the GUI for the player.
Install both the packages and you are all set.

Sopcast
PS: The authors also provide packages for other architectures and distributions. You can find it here.
