We seem to be in an echo chamber, been here many times already:

1. testing

2. firewall avoiding.  As demonstrated by the hackathon.

3. I see big differences in jitter and latency between IPv4 and IPv6.
   I want to characterize the diffeence, then select the best.

Beats me.  All I can see is different paths using traceroute, mtr, etc.

Not unusual for ISPs and backbones to route IPv4 and IPv6 over different
hardware.  They don't tell me why...
