I also wonder if someone could build a Matrix bridge if it is available via web, that would be fairly cool.
Some questions:
- Is it phone-number based IDs? Or can I pick a username or get a random ID?
- Is spam going to be a problem? Previous Apple had the advantage that you had to buy a multi-hundred dollar advice to call someone. Will they need to implement new spam measures (or will you simply have to add a contact first)?
