The retail version of D2:ED used Securom, with just a disk check (no online activation required or limited installs, etc). I doubt DKS would use a much more restrictive copy protection system, though that is usually up to the publisher (Lar mentioned making sure they would have more freedom to release patches for FoV/DKS, if required, when negotiating those deals, so they could have made sure they would have a say in copy protection, as well).
