Re: That's pretty much all it does
"merging two medium-sized companies' private address space is a massively expensive project which can take years to complete"

"It allows larger, flatter networks."
How are large flat networks advantageous? We've spent decades moving away from flat and into hierarchical for many many reasons and you want to go back to flat networks and the massive security fail they are. imagine a company with a giant flat network and 1 machine gets compromised? through some vlans in and some acl's and youve made the infiltrators tasks much harder.
