Complex problems often have complex solutions. I think a lot of people look at sendmail, for example, and go "GAH!" without knowing much of the history of gatewaying between networks and the rewrite rules that facilitated that. But I also wonder how hard we've worked at trying to reduce complexity in some cases. The SIP thing is a little painful because at the time it was brought to the IETF it was touted as a much simpler technology than H.323. And, of course, it turned out that ... complex problems often have complex solutions and there's a reason why H.323 is as complicated as it is (mostly). Still, I wonder if we're just tending to accept complex solutions a bit readily. Melinda
