X. Cost Estimate
Since it was necessary to "cost" a system not completely defined, using equipment never built, the author must absolve all concerned (and possibly even himself) for the errors and inconsistencies that inevitably occur in compiling cost for an untried system, especially one that uses unorthodox construction techniques to fulfill an unknown, but rapidly growing, demand for a new service. This inconvenience is part of the price we pay for new systems concepts.
