Not necessarily. If I browsed through nixpkgs and found some package with an interesting-looking description or path (window-managers/foobar? editors/xyzzy?), I could install it out of curiosity/for testing, and then I'd have no idea that it is a "please pay". For me, a "honor system" here makes much sense. Similar with e.g. http://www.aseprite.org/download/. Also, a possibly interesting question is if something smart could be done for itch.io games, many of which are fully "payment optional", but still "payment heartily encouraged" (i.e. they're free to download, but a payment is encouraged in a way which is very well thought through and unobtrusive in my opinion). /M. _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
