Would you like to have REW to be installable via GNU/Linux distributions such as Debiand and Ubuntu?
This would lower the threshold for people to install it and will add aditional quality assurance and testing.
Yes. It also depends under which license you want to have it redistributed. Then you can have it shipped via Debian/Ubuntu or you can offer a deb repo yourself. Also depends what the dependencies are for the jars. Which version of Java is minimally required.
