Well, GeorgeS' spectres are done. I finished rigging and animating them yesterday. If you'd like to see more models, perhaps you should ask him
I doubt that SC will ever replace a live EQ client but that's really a question for the server devs. My client is just a separate option for people who don't have a compatible live client (with obvious differences, e.g. no SOE content). The official EQEmu login server does recognize SC, though the protocol is entirely different and SC connects to a different LS port for it. The protocol will likely change as we still need to implement client version authentication somehow and I'm awaiting direction from Doodman and FNW on how they would like to handle it. Otherwise, the LS protocol that SC uses is entirely our own invention.
