It should be fairly straightforward. Click the deb, and it will set it up normally.
To uninstall, do a sudo apt-get remove aether on a terminal.
The package should have everything you should need to adapt it to your distro, including .desktop files. Aether has no dependencies so it should be fairly easy.
I don't recommend trying to link to the system versions of libraries instead of what I am shipping. I tried that already. It's a world of pain.
If you end up to adapting it to your preferred distro, please let me know so I can link to you.
In Ubuntu, when the application is started at boot if the user chooses to do so, the application icon becomes a question mark.
To prevent this, pin Aether to your Unity Dock.
This happens because Unity isn't smart enough to figure out 'path/to/aether' and 'path/to/aether -openatlogin' (the flag that starts it minimised) are actually pointing to the same app.
