Since Nomads are a closed faction (or am I living in the past?) give Nommies the cloaks for free.
I'm not saying those Nomad trails should have them, I say the official Nommies should have them, on all ships.
The fuel is a bit of a problem for them, looks like either a new commodity is required or something else. I can suggest a name for the Nommie fuel, let it be "Biomass" to indicate it's organic origins.
I would not mind cloak being available for a fair price on their base, of course it does open the door for some abuse to do it this way.
Another way is to raise the price for vessels to account for cloaks.
They could be added to existing ships with an account price deduction by secret admin power since there are not too many right now.
All up though I believe that the dev/admin team, one of them, decided last mod to move away from giving closed factions better tech or other advantages like this to just leave their RP as what makes them different from normal factions.
