20k (10^4) photons/sec is a TINY amount.
An ordinary flashlight emits something like 10^18 photons per second. Even a star in the night sky sends around 10^8 to your eye.
That few photons is not going to have much bandwidth.

Of course, if it does upgrade to the point that it can move gigabits per second, they'll use it for that. I don't know of a particular reason why this would be fundamentally impossible. I'm just saying that's not a necessary condition for the technology to be useful.
