"He powered up his processors, settled back in his favorite chair, and carefully attached the Portal's five sucker electrodes to his scalp. For long minutes nothing happened: a certain amount of self-denial -- or at least self-hypnosis -- was necessary to make the ascent. Some experts recommended drugs or sensory isola- tion to heighten the user's sensitivity to the faint, ambiguous signals that could be read from the Portal. Pollack, who was certainly more experienced than any of the pop experts, had found that he could make it simply by staring out into the trees and listening to the wind-surf that swept through their upper branches.

And just as a daydreamer forgets his actual surroundings and sees other realities, so Pollack drifted, detached, his subconscious interpreting the status of the West Coast communication and data services as a vague thicket for his conscious mind to inspect, interrogate for the safest path to an intermediate haven. Like most exurb data-commuters, Pollack rented the standard optical links: Bell, Boeing, Nippon Electric. Those, together with the local West Coast data companies, gave him more than enough paths to proceed with little chance of detection to any accepting processor on Earth. In minutes, he had traced through three changes of carrier and found a place to do his intermediate computing. The comsats rented processor time almost as cheaply as ground stations, and an automatic payment transaction (through several dummy accounts set up over the last several years) gave him sole control of a large data space within milliseconds of his request. The whole process was almost at a subconscious level -- the proper functioning of numerous routines he and others had devised over the last four years. Mr. Slippery (the other name was avoided now, even in his thoughts) had achieved the fringes of the Other Plane. (Vernor Vinge, True Names, 1981.)
