Why not just *ask* a sufficiently large sample of businesses? Under
restrictions to only publish aggregate numbers, if needs be. You probably
won't get honest answers about their unpaid Windows deployments, but
there is no big incentive to lie about unpaid Linux installations.
I was under the impression that many (most?) of the Gartner/IDC/whatever
studies are done this way.

the people filling out the surveys are not always going to be the people who know what's running.
over the last 10 years it hasn't been unusual to see a company pronounce that linux is junk and then learn that a lot of their datacenter infrastructure had been moved to linux without the senior management knowing about it.
the people who know how many systems are running linux are too busy getting work done to fill out this sort of thing
