The AppleTV's NIC swap behaviour is triggered when en1 becomes active by joining a wireless network. This mod puts the USB NIC on en0 where it's seen as the primary fixed interface, and en1 remains absent in the OS so the NIC swap behaviour cannot be triggered. The original ethernet NIC is now on en2 which the "AppleTV" part of the OS is effectively blind to so there's nothing stopping you from using it as second interface and it should be a simple case of configuring the NIC using System Preferences.app. As with any multi-homed setup you may need to reorder NIC's and/or set additional network routes to have things work as you want, but that's all standard networking.
NB: I'm still on the lookout for a Broadcom chipset USB Wifi dongle. I'd like to find something that can be set to impersonate an original airport card (including use of the 'airport' commands in the OS) so that the original en0/en1 appearance and behaviour is maintained. I can only find PCI based cards, but if someone spots a USB one, let me know!
