I think this sharing dropped off drastically at some point in fairly recent history. I took a look at Apple's list of services and devices which can be shared with a checkbox or two; it really was a much shorter list than I thought, and I'm sure the most convenient Linux distro has a couple less items again. Windows I'm not so sure about, but I don't think you have to go back many years to find the time when Windows 98 was the most common Windows, and what did that offer to share? Printers and files only, if I remember right. > > Perhaps the old saw about 'ethnics' (pick yer own favorite..) and > garbage. > > "We never actually throw anything away, we just kick it from place > to place until its gets lost." > > Bill > > [1] AN/FSQ-7 and AN/GSA-51, could of course 'share' their resources > - or at lest take-over, one from another.
