I'm sure Dennis will be heard from, and will bring his customary diplomatic balm to bear on this matter, but: note that this is no different from what happens when packets leave your 10- or 100-Megabit-connected workstation and are routed over a T-1 or slower WAN line. TCP already deals with this, using slow start, congestion avoidance, etc. to deduce the amount of bandwidth actually available to it, and throttle itself back accordingly. Your notion that a bandwidth limiter like ET's will cause increased retransmissions is unfounded. Jim Shankland Flying Fox Computer Systems, Inc.
