They don't even do that.  They only control what addresses the server 
advertises in the VLDB.

I can think of ways to redirect traffic coming in on a designated port to 
different ports depending on the incoming interface.  But what you're 
trying to do is have multiple independent processes bind to (*,7000) and 
route the traffic based on the interface it comes in on.

I know of no way to do that, and that's the least of your problems if 
you're trying to run multiple fileservers on the same machine.
