The benefits of cryogenic treatment include increased strength, reduced stress risers caused by manufacturuing processes, claimed resistance to abrasion, and a few other claims. I don't think I've ever seen anyone claim that it makes the parts "slippery as if oild". The main advantages are increased strength and longer life. Popular treatment for brake rotors, since it can double their life in high temperature racing applications. Keith at ws6.com used cryogenic treatment to extend the life of his Baer cross-drilled rotors from 5,000 miles to 18,000 miles. If it made the parts "slippery as oild", it wouldn't be a good idea for a brake rotor.
If I recall correctly, pricing is "per pound", and the cost ranges from $1-$2/pound.
I don't see cryogenics adding any HP... and definitely not 100HP. Perhaps you could build a stronger engine, and make extra HP out of it with something like a little more nitrous, or bigger heads/cam, but the HP doesn't come from the cryogenic treatment, its the result of being able to make more power because the parts are stronger.
Here's one outfit friends of mine have used, and a quote from their webstire:

300 Below, Inc. is involved in the process of Deep Cryogenic Tempering and has developed an advanced, computer controlled processing system for reliably treating materials.
As our name implies, we treat engine components and parts at minus 300 degrees Fahrenheit to improve their properties. Computer technology allows us to regulate temperatures to 1/10th of a degree, accurately manipulating Cryo-treatment in accordance with the mass of your engine part.
Deep Cryogenic Tempering creates a significant increase in abrasive wear resistance and durability. The increases in tensile strength, toughness and stability may couple with the release of internal residual stresses. The end results are longer engine life, higher horsepower and less breakage.
The one-time, irreversible treatment improves the entire structure, not just the surface, giving your engine stability only found previously in seasoned engines. Decrease the movement and increase your engine's performance and life..
