Yea, that's what EvilDragon told me yesterday when I asked him on IRC. However, he also suggested it was something we can look at for a Pyra successor.
Also of note, is that a lot of the concerns that EvilDragon seemed to have with it were things easily solved. (ie: What if two programs at once want to write to it?)
I think it is beneficial to continue discussion. If we bang out some plans and EvilDragon still doesn't want to do it, at least we have set up a foundation that plans for a Pyra successor can include. And who knows, maybe EvilDragon will change his mind if we have a good enough plan.
A third party mod would be useless. This kind of feature will have nothing coded for it if it is not standard.So the Pyra's features are basically locked down and ED has no interest in expanding on that. Commence discussion on how to make this a 3rd party mod.
