Multiple IPs on dial up interface

Is is possible to assign multiple IP addresses to a dialup interface ?
If so how would one do it ?

1. Multiple IPs per interface

Is it possible to set multiple interfaces to the same address?  This would
give a degree of redundancy if one interface were to go down.  I would like
to configure the server so that one address could be used and whichever
interface was less busy took the traffic.

For example, one server had five network interfaces (eithernet, fddi, T1,
whatever).  DNS points to IP XXX.XXX.XXX.XXX as  I want that
IP available to all interfaces so whichever interface gets the data acts on
it.   I assume something like
this is done in high bandwidth sites.  How are web sites configured?  They
can't just have a T3 plugged into one server interface.

Any insite from high volume site administrators on how they are set up is
