Personally I wouldn't mind doing ping/traceroute 100% in userspace.

The TP meter itself does not require to exchange real packets between user =
and
kernel space, but only requires the availability of a command to start and =
stop
a measurement session. I believe these could be implemented as yet another
netlink command/message type.
