never tried it but i assume you could

how i see it this shapes up to work like digital downloads, where you basically lease the game, or you pay a licence to play the game, but you don't really own the game.

It's getting more and more to the point where you don't own the product you think you buy. Technically you buy for the medium but strictly speaking not for its content. Instead of paying for its content, you pay for a license to use that content. However, whereas in the past there were no check-ins regarding the license, it's getting to the point where you must check in at an online service and because you must do so, the service can control the way you use the license you paid for. To put it short: These days, you give control to your console maker of choice instead of keeping it yourself.

no one knows but probably not. they won't want you to share an account with your friend group allowing a group of people to "game share".

I could see Microsoft allowing content to exist on up to x number of consoles. 

Currently, music you purchase can exist on up to five devices you own.  It doesn't matter how many of each, be it 5 Xbox consoles, 5 Windows PCs, or 3 Windows Phones, a Windows PC, and an Xbox console.  Five devices can possess and use the content.

What Microsoft could be doing is allowing you to assign content to a device.  So if you log into your consoles, install content on them, those two consoles will appear as legitimate devices for you to use.  Likewise, you could also remove access to that content from one device. 

For secondary use, they could easily require the disc to be present.  Like it currently is for the Xbox 360, or if you don't want or have an always online Internet connection, require the disc to be inside the device in order for the game to continue to be used.

There are a lot of ways to provide DRM and still provide all the features that gamers want, like the ability to share a game or transfer ownership/second-hand sales.  We just have to wait to see how Microsoft handles does it.

While I understand the business aspect of it, when you say it out loud, it's really quite shocking.

Especially when systems like vita and 3ds allow you to actually play other people without them owning the game, and on ps3 you can actually share digital content with another account for free.

Probably not at same time. But in reality no-one can answer this question yet.

I'm just going to pretend you are your usual confident self and dismiss this reply of "sooo transparent".

365 licenses vary, so it all depends.  I think the standard is 3 or at least my Educational license is.

But the bigger point that both you and I are making is, Microsoft has the technology and ability to solve this whatever way they want.

The Xbox 360 has DRM that isn't significantly different from anything that has been purported to exist on the Xbox One.  In fact, so far, the DRM on the Xbox One is less restrictive in the fact that once the game is installed, the disc is no longer needed for the console to which the game was initially installed.  I can't tell you how many countless times I WISHED that were true with the Xbox 360! 

Activation is a completely different, side issue.  I personally don't think the purported daily online connectivity requirement is a need of the activation.  If Windows and Office don't need it, why would any game on the Xbox One need it?  It may need to do it once, but I think the online requirement boils down to the programming Guide.  Again, anyone who has AT&T Uverse will know this.  The MediaRoom-based Uverse set-top box requires that it phones home every 24 hours to update the programming guide.  In addition, I think Microsoft in pushing updates, is expecting consoles to phone home regularly.  So, I'm not convinced that the software activation requires a daily connection.  It doesn't make sense that it would need it. 

They already said that if you buy a game and your son goes to a friends house he will be able to play it there because of the family account thing. So in theory all you need to do is setup a guest account for the second Xbox. Currently XBLA ties your game to the first console you buy it on but lets you play on any console as long as you sign in to Live, so even if it used this method you could just buy the games on the secondary console and use them on the main console while logged in as you.
