I haven't read the description myself, but the way you put it stircrazy, yeah i agree that those terms are used in completely the wrong sense.

Chad, I get what you're trying to say, but for the record, that isn't why your fingers get wrinkly. The reason is osmosis (water movement) but in the proper sense. Skin is designed so that your salts and stuff stay in you, and the only stuff that leaves is whatever is actually on the surface already (salt from sweat, various oils, etc). Water is small enough to flow through and fill up the skin cells which expands the cells. This happens wherever your skin is in the water but your fingers/toes get wrinkly first because these parts are more rigid from callouses. Its kind of like the finger tips are rigid metal which buckles under stress, and your other softer skin is like rubber which is flexible and will stay smooth under this stress.

There's a few guys using them over on both the Zeovit board and RC.
