Or for the ISP or multi-organization NOC, one Murder of servers that
support multiple domains.

The former is more useful I believe than the latter. If you had one server
per domain, then you have no redundancy and it would be simple enough to
just point each organization at their own server.  So the first idea is the
only one which actually provides new functionality.

I believe that the frontend should get the domain from the IP, and forward
to the backend as a fully qualified address.  The backends only need a
single IP.
