Is someone at Mozilla willing to share some technical details about how this is implemented under the covers? The main thing I’m curious about is:

Can the ability to have multiple relay numbers tied to 1 real number be added relatively easily by scaling your technical architecture, or is there some non-marginal underlying cost to each additional relay number that would make such a feature too expensive to support at this price point?

As I understand it there's a cost to every number, which is why we're limiting it to just one number at the moment. (Though we'd definitely have loved to implement it the same way we do email masks; if we do find a way to cost-effectively do so, I'm sure we will.)
