The following communication was sent to me privately and I am accordingly omitting the author's name. His point, if I understand it correctly, is an important one. The Justice Department claims that Microsoft's browser, IE, is a 'separate' product, not an 'integrated' part of its OS. Justice has not, so far, asserted that any of the OTHER components of that OS are 'separate' products, i.e., are stand-alone product 'markets' in their own right. Reiser, on the other hand--according to my correspondent--has done just that. His case rests on the premise that not only is Microsoft's BROWSER a separate and distinct product--independent of the underlying OS--but so is a component called 'FILE SYSTEMS.' A 'slippery slope' here? First ban the 'integration' of a browser into OS, then (per the Reiser case) make Bill open up his OS dominance of 'file systems,' and after that go on to all the OTHER current OS parts, making him disgorge each of them into the open market where his version would have to compete on price and quality with that of upstarts like Hans Reiser? Peel away everything but the final, INDIVISIBLE core of OS? 'Deconcentrate' Bill's ultimate monopoly, his OS? Scary, right :)?

Charles, Reiser has made Microsoft's case against Justice for them. That is, he raises the issue I raised once before: if the browser has to be separate from the operating system, why shouldn't each component of the operating system be treated (be legally required to be treated) as a separate commodity? Antitrust as an approach to public policy presupposes that commodities are distinct identifiable items, distinguishable as potatos are distinguishable from tomatos. One can then define a market for a commodity and count up the number of competitors, and say unambiguously if buying one commodity is "tied" to buying another. But computer software consists of lists of lines of code. Why draw the boundaries between commodities at one place rather than another in the list of lines of code? Conversely, suppose the law should, as Reiser suggests, require that each "component" of an OS be separately available for use with complementary code produced by competitors. What would happen? The application software I buy to keep track of my postcard collection would require one set of "components," and the one I buy to scan and print the pictures would require another suite of "components," and one wouldn't work with a system that would support the other, and I would be out more money for less functionality. I think that would work in Microsoft's favor, when all is said and done -- since the only compatibility standard would be the brand name, and Microsoft has the brand name. Indeed, that's their strategy in a nutshell, and it would work even more splendidly in the legal world Reiser envisions.
