Prelude

One of the issues with NationLands over other civ servers is that international rail systems cannot be protected in the plugin.

I am looking for some feedback on this problem

A Possible Fix

The fix that we have thought of is the following:
* Modify and Install Citadel
* Only allow protecting of Rail blocks
* Rails protect the blocks underneath them
* Citadel protection does not work in claimed territory

The way rails protect blocks underneath them is that when the block underneath is broken it sees if a rail is above it and is a citadel protected block. If it is then it stops the block being broken and decreases the durability of the rail by one.

Possible Issues

Immediately our thought was someone using this to make reinforced bases outside of claimed territory that would be hard to get in (think reinforcing the rails with diamond and surrounding your base with that).
A few thoughts on this is one or more of the following:
* Only allow stone level protection
* See if there are a lot of rails around and stop protection in that case
* Not sweat it since people could break in, just takes a while

Trying to run the rail might go through a third nation that has claimed land, players will have to do the following:
* Work with the nation and have them build that stretch of rail
* Go around the nation's claimed territory

Another Idea

Use either particular block type, FactoryMod recipe block, or command to create/set a block to be the start of a protected rail and another corresponding block to be the end point. Any rails placed in this line are protected against direct manipulation.
Some properties for this rail protection system * Costs 1 Power for each rail protection every 10 blocks of protection (crossing the map costs 1000 power)
* Each rail protection beyond costs twice as much per 10 blocks than the last
* The ending blocks are not protected themselves (and do not count against the block count for power)
* This will protect rail blocks and the blocks that are underneath
* Fluids will not destroy rails protected in this manner
* The end blocks need to be either on the same X or Z coordinate and be on the same Y height
* If a nation claims land that contains a rail, they can edit it as they see fit

Example:
If a nation has one rail system that protects 100 blocks and another that protects 200 blocks then it cost that nation 60 power (Every 10 rails costs 2 Power, the first has 100 blocks so thats 20 power, the second has 200 blocks so thats 40 power)

This makes it progressively more expensive for each rail system beyond the first

Feedback

I want to know what you think of this idea for the server. It would not mean that citadel is installed and runs as normal like Civ this is just for Rails.
