For many, the price of the authoring package is the first thing they notice. However, there is a second component of price: the runtime fee, ie. the fee that software manufacturers demand for distribution or licensing texts produced in or for their systems. We believe that authoring packages should be priced similar to a good word processor, certainly no more than $1000. Runtime fees must be very inexpensive or free; in order to be competitive, hyperbooks will have to be priced comparable to paper books.
