Personally, I like to think that Rin and Len were originally going to be just one person (in other words, just Rin), but due to a mishap in Rin's creation, they were split into two separate beings, one boy and one girl. This goes with my headcanon of the Vocaloids being artificial beings who live in a sci-fi-fantasy-esque world seperate from our own.
