Nay, for if we reduce the communications bandwidth, we need not
go to optical frequencies. These wispy interconnect cables, a few
dozen microns or so in diameter, can be used to carry simple
electrical signals at a few thousand baud. With sufficiently high
impedence, communications between nodes could be carried out
using very little power, a nearly negligible fraction of that collected
by the nodes.

The question becomes, what is the nature of the communication
between nodes? Will a few thousand bits per second be sufficient?
