I've got an arrangement where the obvious way to do things is with a Viewable... class StorageThing(pb.Viewable): def view_setMessage(self, who, what): self._store[who.identityName] = what class Who(pb.Perspective): def setMyMessage(self, what): self.storageView.callRemote("setMessage", what) only, it turns out that some of the "who"s don't really need to be in a seperate process from the Viewable; storageView is actually a reference to a ViewPoint instead of a *remote* reference to a ViewPoint, and ViewPoints don't have callRemote (because, well, they're not remote). I don't know, maybe PB just isn't quite as transparent as I desire it to be. I did so much like the idea of writing this code to communicate locally now, and just being able to drop in remote objects instead later. I could of course do def setMyMessage(self, what): self.storageView.view_setMessage(self, what) but that doesn't look nearly as elegant, and I'll have to make duplicate code with a callRemote if storageView ever becomes remote.
