To be honest I would not expect that any time soon. If you consider
that your interfaces can be on different SIPs and that near realtime
communication between is required to do shaping or policing you can
see the complexity of the task.

Since we encountered exactly the same problem we decided to go down a
slightly different route. We only use 2 links (or potentially 4 links)
EtherChannels to allow for more equal load balancing. Then we apply
somewhat more relaxed (in comparison with what we want to achieve)
policies to the physical interfaces that constitute the bundle. It's
not ideal, but so far this is the only way around we found. This is
for outbound only as well. For inbound traffic we relay on the other
end of the links.

kind regards
Pshem
