We often used a house rule regarding access to neutral major powers, we thought it was unrealistic to disallow an army to enter a neutral major power, its not like its a massive wall around the border and its not like a local official even if he dared to stand in the armys way would be able to force an army to turn around.
To deal with this we used two different house rules.
1. Nothing stops you from entering a neutral major powers territory but each turn you do, or keep a corp inside such territory it costs you one political point for each major powers border you intrude.
2. At any time when a corp controlled by a major power enter your controlled territory its concidered casus belli and you can declare war at the controlling major power at no cost, this even if there is an enforced peace.
As you see, the penalty for violating someones border can be substantial, it was at least enough of a deterant to make it extremly unusual for someone to actually activate these rules. I think that concidering the current repatriation rules and some other silly scenarios, it might be worth to concider something similar in EiANW.
