Ok this is a great article... but what is Flockport stuff? I'm kinda shying away from Docker since their move from LXC... This looks really neat!
The comments are spot on, most networking gurus appear to be strictly against extending layer 2 as we note in the post but we wanted to put the options out there. You definitely need to address latency and mtu issues across remote hosts that will crop up, but with standards like VXLAN based on extending layer 2 perhaps we will soon start seeing interesting workarounds.
