I understand that this currently a service for significant others, but I would suggest you think about the option for multiple accounts in non-romantic situations:
A person you are temporarily "paired with" in a work project, a creative endeavor, a trip, etc. I'm writing a book with a colleague who connects most often via phone, but is hard to get to otherwise. It would be great to Pair with him until the book is done without having to "Un-Pair" from my wife.
