E John, et al, Technical work is best guided by substantive case analyses or, at least, documentation of a range of concrete, real-world details. Having a general assertion, of the type you offer here, is useful as a starting point in discussion, but not as an ending point. What is needed is followup that provides details that compose a serious and substantive case for the utility you describe. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
