Pipelines are possible, but they take time to build. The pipeline would have to cross several countries (depending on what route is taken - look at a map) which makes it much harder. Will Oman even be interested in this? Saudi Arabia I guess could build a pipeline to the red sea entirely internally, every other country in the region would have to cross someone else.

Still if Iran does charge the $1/barrel of oil they are proposing expect the countries in the region to look into a pipeline. That is a lot of money and a pipeline could potentially be cheaper in the long run.
