It takes approximately a year to learn to walk after you are born. But almost everybody figures it out. And once they know, they practically never forget. So I don't know, is it not trivial? I have never had to support all of the mobile environments of DropBox nor the scale, so I cannot claim that my 99% solution would ever meet their 99.999% requirements. But I have been able to package Python apps for Mac OSX, WinVista, Win7, Ubuntu, and CentOS at the same time using that strategy.
