Hoglet 4 PC art net out?

I have a couple Hoglets and a laptop server w/ a super widget. I have successfully networked the consoles. I wold like to be able expand my capabilities and output Sacn or Artnet. All of my PCs have only one network card, and I have been advised against trying to use the same card for both networking consoles and outputting cat6 data. Does adding a DP8000, which i believe will out Sacn or arnet, eliminate the need for a second network card? or will I finally have to upgrade to the Road Hog?
