Fast photon to photon communication?

Is there some way to send data to another photon faster than once per second?
We are trying to put a photon on a drone with some sensors and then have a second photon control the controller to fly it.
We can use Particle.publish(); and subscribe, but that has rate limit of 1/second.

Is there something faster? I found a bunch of things that all seem to be based on publishing data to server faster, but nothing for reading data.

TCPClient/TCPServer and UDP.
