Hello All,
          I've spent some time messing with silverlight on feisty, and
have some notes I wrote down while getting it to work. See if these
help. They replace the built in mono stack with one from svn, and
install everything needed from svn.

Let me know if it works for you guys.

Install Ubuntu 7.4 onto your test machine or VMware image. [link
http://www.ubuntu.com/getubuntu/download]
Update using build in updater.
        This prepares a base to build our moonlight stack upon. Any ubuntu
7.4 machine could be used here instead.

sudo apt-get install autoconf automake libtool build-essential bison
sudo apt-get install prevu
        Little bit of explanation here. One of the required libraries
(libswscale-dev) does not exist under 7.4. 7.10 has a copy, but it's
not part of the traditional backports repository. Prevu is an
application which creates a self-contained build environment (similar
to gentoo's emerge) to build a .deb file of a 7.10 program/library for
7.4.
sudo prevu-init
        Sets up the build environment. This could take awhile. Answer
yes when asked
Edit /etc/apt/sources.list as root and add "deb-src http://us.archive.ubuntu.com/ubuntu
gutsy main universe restricted multiverse"
        Add the repository for gutsy (7.10)
sudo apt-get update
prevu libswscale-dev
cd /var/cache/prevu/feisty-debs
sudo dpkg -i *.deb
        This installs all the packages build by prevu. Ignore the ones about
ffmpeg not being able to be installed
