How about combining the two ideas and make a slight expansion on Badgers idea
How about creating a new conneticut (or using the existing one perhaps relocated on the nav map) which contains 6 (numbers used for representative purposes only) Jump Holes all along way apart. Each Jump Hole leads to a "private" system as described by Igiss (these could be linked to allied NPC systems via JHs eg Bundschuh sytem linked to frankfurt but might create easy travel routes). Therefore attacks on enemy systems could be mounted without flying through other factions/clans teratory and once a system was captured the capturing faction could reach it more easily without the same problem.
PS this sounds a great idea, it would also give mercs a way to find jobs by flying between systems.
