RE: 2 NIC's on same network, possible?

["David Gillett" <gillettdavid () fhda edu>]

  Short answer:  No.  Teaming means they look, to applications 
and the outside world, like a single adapter with the aggregated
bandwidth.
  If the adapters go to different VLANs, you have a multi-homed box.
If the VLANs have overlapping address spaces, you've got a really 
interesting mess on your hands, and if they don't then you can't
usefully give the same (teamed) address to multiple adapters.
