I think that the 'Honorverse' style FTL comms would work rather nicely in this universe.
The first generation FTL 'grav pulse' comm was slow and clunky, omnidirectional with a low absolute range (relatively speaking) and a high space and power requirement.
As the series progressed, the FTL comm got better, to the point where an extra-large 'Apollo' missile could serve as a high bitrate ftl bridge for a pod's worth of missiles, and FTL voice comm was plausible where sufficient relays were available.
the grav pulses can be generated by any sufficiently 'smart' grav drive, and read by anyone with appropriate sensors..
now, if they can decrypt/understand what they are reading is another story.
With some modification, this would fit into the fenspace universe, imo.Wire Geek - Burning the weak and trampling the dead since 1979
