Well, yeah. Have you priced out a quarter micron fab lately or looked at price lists for multi-layer PCB manufacturing equipment? The general public doesn't have widespread electronics manufacturing because the up-front and operating costs are both orders of magnitude above what you need for software, and because (again) a minor tweak of hardware involves disproportionately more cost than a minor tweak of software. > Personally I'm not buying it.

I have been on the design teams for an ASIC and a full system that required custom PCI boards. I have a reasonably accurate idea about the manufacturing costs for hardware, and those costs are all my email talked about. I ignored the design and testing costs, since free software has shown that you can amortize them across users. The manufacturing and distribution cost for software, on the other hand, can be effectively driven to zero. When the cost to produce an existing third-party design (making no changes) is five or six figures, there is not much reason to freely license whole designs. That cost is not your own labor: it is what you need to pay the companies who own fabs or PCB mills to build your design. The economics demand added value. That is why opencores.org deals with logic cores and proto boards rather than retail products. Michael Poole
