List of non-free software in Ubuntu?

Anyone knows if there is anywhere a list of all non-free software included in Ubuntu, preferably the newest Edgy release?

The idea is to just make a simple script that will remove all non-free software from Edgy making it a fully Free Software installation, even though the user would still have to watch not to install anything non-free from repos. If you want a fully free Ubuntu you can consider trying gNewSense (personally I think they could use a better name, which I told them).

Anyway, I'm just kind of weirdly motivated to do this script... I'm in a kind of weird situation where I am eager to use a 100% distribution with user-friendliness and package support of Ubuntu, but the existing project which offers something like this (gNewSense) isn't exactly cutting it. :\ It is making me wish to fork the whole thing off and create my own Edgy based distro which would be Edgy, but stripped of non-free stuff and with my own marketing efforts (something GNU guys tend not to understand too well apparently). Maybe I just have too many freaking ambitions.., not to mention that my current internet connection doesn't allow maintaining a distro project (though I'm hoping for WiMax to come here soon). Who knows where will all this end up...
