You can use "ifconfig ... alias" to bind more than one IP address to a NIC; 
you must you a different subnet mask, however (usually 0xfffffff).  You also 
can use netgraph (ng_many2one?) to trunk several NICs together for 
fault-tolerance.

It was not clear to me which capability you were asking for, or maybe it 
simply is the case that you're asking why someone would do this?
