Well, you could - but use two sets of wires - one for power, the other
for data.
The problem is that what's a clever idea for connecting motors (rotate
the connector 180 degrees to reverse the polarity) is a disaster for
data connections because it adds more electronics into every 'module'
to protect it against reversed current - and to make it actually work
no matter which way round with some kind of auto-detection mechanism.
Not nice.
I think a simple stereo mini-jack would work best...three wires - small,
light, standard (and therefore cheap).
