This triggers many questions. - in your list of discovery technologies, why no UPnP ? - are you saying that the discovery plugin, or web introducers, or both, are relevant to this task force ? - how is this discovery plugin connected to Web Introducers ? I see the complementarity, but not the connection. About the complete system using both for letting a page communicate with a device: - do you manage the (same) device disappearing and reappearing on the network ? or is there user intervention required for each connection ? - do you have a notion of authorized device (or paired device) ? - how does a device communicate with a page ? is there a sort of postMessage from the device to the page ? or do you have a "ghost page" per device to handle that ? Do we need the confidentiality of Web Introducers ? I do not see why. With UPnP, messages are structured (not just a string). How would this be dealt with in a message from a device to a page ?
