A good reason to have pipelines between parts of the country that could move gasoline, diesel, natural gas, or propane.

But then that would make sense, and considering how Keystone pipeline has been shot down by environmentalists, probably will not happen.

I would rather the private sector handle these problems rather the government.

Due to the differences in vapor pressure, it would be difficult (expensive) to share a pipeline with gasoline & propane. Diesel, Gasoline, Jet Fuel typical all move in the same pipelines in batches.

Natural Gas requires even more expense to combine in the same line with liquids. At every compressor/pump station you have to separate them then recombine. I only know of it being done for long offshore distances, even then it is uncommon.
