[Click] generating artificial delay

[Simon Schuetz]

Hi,
I am doing some network testings and I need a tool to generate some
artificial delay on the intermediate router (lets say 100ms from
incoming to outgoing) to simulate some sort of network. I need the
support for Linux IPv6.
Is it possible to do this using the click router (either userlevel or
kernel modules) with a configuration like
FromDevice(eth0) -> DelayShaper(100) -> ToHost(eth0) ??

If not, any other known tools that support such a scenario?
(Dummynet is for BSD only, NISTnet does not support IPv6)

Thanks 
Simon
