Are you aware of our concept of the Nether Network? (Original Thread:

It may be awesome to combine these two.
Basically, the idea behind the Nether Network was to have a kind of style guide, so when people build new ways from portal to portal, the roads are built within the netork, so other people can use them too and dont have to built all the way.
It's mostly thought for longer distance travels and transport of livestock and villagers.
Basically, the Network Roads are right under the ceiling of the Nether and then the Portals are connected via staircases.
I have to admit, that the project collected a bit dust, mainly because the region system doesnt make it such a requirement and most people already have what they need in their bases.
Oh, and we originally thought about a hub system, but abandoned the idea because we thought a highly adaptable system without a central point was just a bit less recource intensive. And we wanted to see if people even use it. But I'd love a hub and maybe some 'Main Roads' into different directions (especially 1.8 land!)
So far I only did one long line from Diamond 9 to Vine which also connects to Oxfordia, without any fancy ice or railways. I think there are some more, though.
I wanted to take a look anyway and do some maintance (Warning of unsafe ways with signs and wood dors ect.).
So, this was a bit long, basically, I wanted to remind you of that. Maybe you'd like to adapt your Nether Hub to that system, so both projects benefit (yours from already existing roads and thought-out systems and the NN from more infrastructure)
