You definitely have a point though in many cases we aren't interested in the user's actual identify. MyID is mostly aimed at developers who have multiple applications but need to know the actual unique number of devices they're installed on. This is particularly important to advertisers who may have many different applications.
So true. In fact, this is one of the main reasons (in my opinion) that Node.js has seen such explosive growth. A package manager makes sharing code, keeping it updated, etc., so much easier.
In fact, it would probably be pretty simple just to create a little "packager" tool that packages the code into a special homebrew formula.
After all, this is what homebrew is for. Why reinvent the wheel?
Ruby not your favorite language? ;)
