Thank you Derek - this is the one piece of Trent's rhetoric that I couldn't solve. Seems obvious now that you say that. If a piece of software is comprised of, say, ten components, and each component must be licensed individually, it is less practical than the same software with a single license holder. It has nothing to do with what type of license it is. Suppose, for example, that someone writes a spreadsheet (A) for doing commodity options pricing. Someone else adds a dependant spreadsheet (B) that specifies spreadsheet A for metals. A third person writes a spreadsheet (C) that specifies B for precious metals. A fourth person writes a spreadsheet (D) that specifies C for platinum. You have an end product that is just as hard to license for commercial resale regardless of whether each component spreadsheet is licensed under a "no resale" license which must be negotiated independently or a "no proprietization" license which must be negotiated independently. ---------------------------------------------------------------------- "We're on the threshold of a whole new system.
