Hrm... what about services like telecommunications? Being in space already, the Fen would have direct access to their own satellites - satellites that can be serviced and upgraded regularly and therefore have much longer uptimes and lifetimes than their competitors. Not to mention the simple fact that it doesn't cost Fen much to put a satellite in orbit. The end result would be that Fen can undercut the cost of things like satellite phones, broadband internet, and digital TV by a huge degree.
Another avenue of attack would be StellOil. Cheap fuel provided in vast, inexhaustible quantities won't make you friends with the EPA... But if you manage to undercut the cost of the competition enough then customer companies are gonna adore you while the competition might put a price on your head.
