Dear all, Web Intents, as in the current draft, is implemented entirely within the User Agent. If the UA does not know of an intent, it cannot be invoked. In a sense, the way the spec is written, the Web Intents Agent MUST be the User Agent. I think that is wrong, architecturally speaking, in the sense of "architecture of the web". I remember a discussion about a hierarchy of intent directories: if the UA does not know about an intent, it should pass the buck to a higher authority, possibly recursively. The model is that there may be an intent register at the device level, one at the home level, one at the ISP level, etc. The way the draft is written means EVERYTHING has to be done by the UA, and I do not see how the model I describe could be realized with the current draft. From a different point of view, I am sure there is a missing feature here, in the sense that the directory of intents that is meaningful to "me as a user" is NOT tied to a browser, nor to a particular computer or computing device, nor to a location (home or office), etc. So the current draft is "mistaken" in focusing everything on the UA rather than on the user. It is OK to have a default implementation of the Web Intents Agent (WIA) inside the User Agent, but it should be possible to supercede it with a more powerful implementation, or one with a more secure approach (e.g. webinos). For example, the UA-native implementation would just have one single, non-hierarchical WIA. But then, if I am an advanced user, I should be able to switch to a WIA e.g. with multiple "circles" (me, family, friends). And I should be able to share a Web Intents configuration regardless of which browser I am using at any time or on any device (specially if the device forces me to use one browser). Does this make sense to others ?
