I think having a dedicated server tool for D:OS2 would be boon. But I don't think that by default, the OC is going to be able to support something like that, it would have to be use with custom campaigns that are built to support that kind of stuff (say, persistent servers or arenas or something).
Then again, I've never tried doing a dedicated server for like Neverwinter Nights 2 OC or something, it just doesn't seem feasible.
