FYI: Starfire is the game that David Webber was line editor for, and from which he & white wrote the first two novels from; it's not uncommon for grogs familiar with it to use it in place of Bk2/Bk5 by adding jump drives and jump fuel, or by making route lines on their sector maps.
Also, the Honorverse is, at least in the first few novels, very clearly derived from starfire (I can even count the turns played in the battles in On Basilisk Station), and the Honorverse was licensed to Hunter for a while. I've seen the playtest files.
So it's two removes for official, but one from use.
And it's a clear example of a type of FTL setup where no FTL comm doesn't make for no comm faster than a courier can get there.
I can understand the interchangeability of the tech and setting, and where one is derived from the other. I just don't like it much as a game.
Having said that, it could be another example of how to import another setting into Traveller, or export Traveller into a setting to give it RPG elements for a game that is primarily warsim.
It probably wouldn't do to directly mention competitors, say Jovian Chronicles or Blue Planet, but it might be a good idea to tout Traveller's virtues of being portable to other games.
p.s. I really do miss Hunter.
