Applogies for being vauge but I once saw a demonstration from Intel showing
two 100Mb nics plugged into a switch. If both the Nics were available then
both would be used, if one failed only one would be used. My understanding
is that this system requires specific NICs and support on the switch but it
did seem to work quite nicley. This was about 2 years ago and I haven't
seen anything about it since.
