That's exactly why.  In my case I had machines with 3+ interfaces and
that way it didn't matter which I decided to use.  Along these lines
you can also assign multiple IP addresses to a single node.  That's
necessary if you want to be able to switch networks after a node comes
up.  I've done that in a case where I didn't have the driver for the
new/exotic network on my boot media.

beoserv will decide which address to serve back to the client based on
the address/netmask of the interface that the request came in on.
