NVIDIA nForce 590

I was reading this review when the following paragraph jumped out at me:

In addition to FirstPacket, the nForce 590 SLI also sports an EtherChannel-like Gigabit Ethernet teaming feature dubbed DualNet. DualNet takes advantage of the nForce 590 SLI's pair of GigE MACs by combining them to act as a single networking controller. This double-wide Gigabit Ethernet connection can be used to push additional data. If one connection fails, the second will maintain service, adding a measure of fault tolerance. NVIDIA declined to reveal exactly how it presents the nForce 590 SLI's dual GigE controllers as a single unit, but admitted that the scheme involves "playing some games" with ARP spoofing, among other tricks.

Does this sound like a disaster in the making to anybody else? Some kind of weird Psuedotrunking setup, details not available, from the fine people behind ActiveArmour.
 
The new ATI RD580 (or at least the DFI that I own) also supports this. I wouldn't use it on anything but a home network that's for sure.
 
It sounds similar to NLB in Windows which "plays some games" with ARP spoofing and other tricks.

Problems with normal operation don't worry me, but I'm betting the circumstances in which the scheme will work right are very limited.

So I guess no worries here.
