Maybe something like this? Just a sketch.
yes this one with a bit more. it reminds me of telephone or $$ exchange graphics, showing the ease of movement across the entire sphere.
mayhaps the globe can become more earth like . at least representationally to signify the the whole.
the N maybe expanded up on by perhaps using the three vectors of N to represent movement around the globe. with the N being the then nexus of those vectors.
otherwise, the N as is suggest a spiral to me, if you continued on from the ends of the N as is you'd end up spiralling around .. spirals are cool
it also suggests a spring. both are indicative of movement to me - which is good.
