	Hence it would be really sweet if the link speed test could be perfumed against the CMTS/DSLAM as these should be powerful enough to handle load from the number of subscribed “homes”. All we need is a fairly cheap way to measure one-way delays to and from the home router… (I think I am just going to try how far supported and how useful ICMP timestamp requests are, I also wonder why these are considered a security risk and seem to be missing in ICMPv6)
