Occurred to me that it would be pretty easy to create an app that downloaded and installed proprietary applications for new users.
tar xfv ./skype*tar.*
cp -a ./skype /usr/bin/
cp -a ./skype*desktop* /usr/share/applications/
cp -a ./sounds/ ./lang/ ./avatars/ /usr/share/skype
rm -r ./skype*/
Paste the above code into a text file, call it NAME.sh, and run as root and it will install skype for you.
This could be done inside an app that could give you the choice to install several such programs.
My question is what is the legality of it. Does the fact that wget is used to pull the program in question from the program providers site, mean that the program owner is actually providing the distribution. If so this may be a perfectly legal way to make these programs available.
