> protocols and systems to help integrate the future rather than more apps

iMessage is kind of the opposite from what this is implying though, right? It is by definition an app (and extremely closed one at that).

I would think that regular SMS or even just email would be more inline with "protocols and systems".

(I have dabbled with a similar thing for myself using my twilio phone number over regular SMS)

I agree with you, iMessage ubiquity obfuscates the fact that it is also a client app and we would be much better off with an open protocol behind it. Would that then be RCS instead?
