	Yes, but note that steam is a compressible fluid, as is air.
	Super high pressure air lines are way denagerous when they
	spring fine leaks.

	Anyone recall if saturated or super saturated steam is
	compressible?  I do not recall the precise definitions
	of the terms, but I think they are compressible.

	If you can maintain the same pressures in a noncompressible
	fluid, e.g. a water-jet cutting head, then the effect will
	be the same: SLICE!
