It's a complex relationship, the dynamic of which is currently being driven by the territorial urges of DAZ and CL. To a therapist, symbiosis=co-dependency. My guess is that there's enough market to go around--but if there's going to be a casualty, it'll probably be the least-established player: PoserPros. And it's worth noting that R'osity hasn't exactly cornered the market on alienating people--PP's got a pretty strong track record in that department, too, especially considering how small they are.
