I also notice you answered the question, but not in the way anyone who needs to depend on this service would want to hear. So yeah you're doing the Mac Mini thing.
I'm with landl0rd. This service should not exist, you should feel bad for creating it, and every time I get a spam iMessage I will think about you and curse your name. Hope the money's worth it.
Are you implying you'd be cool with it if it was Apple sanctioned? That's pretty silly.
It’s pretty obvious that they meant that anyone who depended on their service would/should probably run away kicking and screaming if they were looking for a dependable service that will do what they claim to in the long term.
If they were Apple sanctioned, then at least you’d have some reassurance that the service won’t die randomly one day when Apple has had enough, à la Beeper.
But then just ...Um yes? I trust Apple to keep a handle on their iMessage network. Citation: having used iMessage for ~15 years. This would mean things like ensuring that I didn't get spam. Ensuring actual company identity (does anyone remember Messages for Business?) &c. This is pretty obvious and I am trying to understand your comment?
