In current datacenter services,user can select type of service by expected traffic.
traffic is small-VPS->Dedicated Server->Housing Service--traffic is huge

In housing service,router based 6rd CE would be fine.
If user would select this architecture,user also can use some native IPv6 technics such as loadbalancing.

I mensioned on section-2.
http://tools.ietf.org/html/draft-sakura-6rd-datacenter-00#section-2
 -For Housing users, there are two options.  Either the 6rd CE
function is performed on the Gateway router itself, or the servers themselves can run 6rd directly.

But I felt it need more detail description.
The former is for huge performance request users.
The later is for IPv6 small start users who not needs server load balancer.
