User blog:Anonymous ONI agent/Covenant Nanobots?

Last night I was having trouble going to sleep, and I started wondering how the needler's tracking mechanism worked (don't ask why I think about this stuff, I just do) Then I had an idea. What if they're made out of a sort of intelligent crystalline nanite composite? That would exlain a lot. But is the Covenant technologically capable of producing something like that? I want know if anybody has any idea whether or not they are.
