Not if your client talks _directly_ to the 400 or NT. But consider using a
middleman server. Then your client talks to _that_ server, perhaps with
some setting or parameter that identifies the backend server to talk to.
The _middleman_ is the one that knows how to talk to every backend you
have—your client needs to speak only to the data 'sales rep'.  :-)
