How lucky you are ;-)  To imagine that I once complained about telecoms

Basically, I'm trying to prove to some network people here that both
bandwidth and latency affect throughput on TCP conversations.  For some
reason, they aren't admitting to this.  So, to prove it, I was hoping to
build in a configurable delay somehow...

I'm gonna try to take a look at this ALTQ functionality, but that seems to
be more QoS related; but, then again, I haven't looked in depth at it yet.

Thanks for the Wed. morning humor.
