No. Long time ago one company approached us asking about support for
many hotspots, each using the same overlapping address space. Kea would
see the packets coming from different relays. The company disappeared
soon afterwards and nothing came out of it.

Since Rob asked it, I though it may be a good time to do a quick
experiment. That's it. Just wanted to make it clear there's no secret
plan to develop anything in that area.

I don't know anything about vrf, except quick look at this:

If you want to have overlapping address spaces, comments from my earlier
mail apply. If you want Kea to just be able to provide addresses over
VRF interface that are globally unique, we can explore this a bit
further. How should Kea open sockets here - one for each vrf interface
(10 customers = 10 sockets)?

We already have a knob for setting outbound interface (search for
outbound-interface here
https://jenkins.isc.org/job/Kea_doc/guide/kea-guide.html). There are
some improvements coming in that area soon (http://kea.isc.org/ticket/5515).
