per-destination host AND port egress rate shaping.  if someone tries to send

IP address, then you can safely RED their overage.  this violates the whole
peer-to-peer model but there's no help for that in the short term.  if some
internet cafe has a CuCme camera setup then you can find a way to let that
traffic off-net without rate shaping.  this will be the exception.
Please be aware that this could have unintended consequences, and should be used in very constrained ways. In particular, there are any number of applications, including VPN applications that use port 80. I would recommend that only specified destinations get such treatment, if you apply it at all.
