Then you just move the routing problem to your gateway/router, and it'll end up exploding because of too many routes in the table (one per container), instead of only one per container host.

Or maybe I'm wrong. :)

if its a flat network then there is only one route. The ARP table might be bigger, but thats a different issue.

There is no difference between this and VM hosts.
