I have this idea, which I think would be useful in this world of many different OSes:
I suggest that you would make it possible to, for example, configure the VPN connection on Windows Phone. Windows Phone has the possibility to configure VPN profiles at the settings, and so do many other OSes that are not supported by Freedome. This would also solve the problem of having no VPN on Linux.
Of cource it wouldn't be as easy as pressing a big button, but many privacy-aware users would benefit from it.
