That's why I think setting materials, that can be dropped into almost any setting, with plot hook ideas (and not spelled out modules), would be where ICE should head as a baseline, with Shadow World being the possible exception to that thought.
I suspect that the supply of good authors is limited enough, and ICE small enough, that it's going to be hard to create and support a setting for every system. I think keeping up with and adopting Shadow World as official might be the best bet for RM, with freelancers here and there contributing more generic works that could be dropped into it or used on their own by GMs that have their own custom setting. I also think, moving forward, all setting materials should be dual stated for RM and HARP. There's just no reason not to IMO.
Although... digital publishing and print on demands take a lot of the risk away from ICE. The way the Channeling Companion is setup, that being that I get my royalties automatically funneled to me at the time of purchase from the distributing site, takes risk away from ICE, leaving the major issue being ensuing the material itself is quality work in the first place (you don't just want to green-light everything thrown at you). Unless there are problems Nicholas is aware of that I'm not, it'd be a win for everyone.
