So... How is Microsoft going to ruin the "your family" loophole?

Unless pre-orders are really low, MS will probably stick with the policies they have.  I think any changes now could result in more bad PR.

Well, my guess is that you can have ten friends, and at any one time, a single one of those friends can play a single game that I'm not playing.

They use the words "any one of your friends", and "at a given time".

Through just plain english this says "one person at a time", though it resembles "anyone at any time"

"any one of" (and not 'anyone' or 'any of') = one of a group
"at a given time" (and not 'anytime' or 'at any time') = at one specific time.

That's my call.

Which basically, as you theorized, makes it exactly like the psn system, because on psn, I get two licenses, and I can share one account with 9 friends and any one of my friends would then be able to play a game that I own at any given time. Notice my wording there.
