Re: Apple have got this right!
For £79 you can join their developer program - which, apart from everything else, gives you a Developer signing certificate you can sign as many of your applications as you want with. And that, coupled with their new notarization service lets you distribute trusted software to your customers that will run on their Macs with no warnings - without going anywhere near the Mac app store or paying anything else to Apple. ... for one year.
If you don't rejoin then your cert expires and no one can install the app anymore.
