    I think this works in a very small environment, but doesn't scale too
    well. Since the tap ports aren't participating in an Ethernet network
    the way a normal host does, there is a real opportunity for collisions.
      Especially when using a hub which is real dumb about things like this.

    It's all about your budget and needs, but for a little more money you
    can get a Cisco 2900 (or whatever vendor you prefer) which can mirror
    both Tx and Rx ports to a common port without the risk of collision.
