On a tablet, TV or car too.

OK, how I'm supposed to open any documents I downloaded from the web?
How can one implement an application like younited
http://www.younited.com that syncs selected user content like photos
taken with Camera application or contacts stored with Contacts
application to cloud?
On my Lumia phone I have three different camera applications and I can
attach photos taken with all those applications to my Facebook post. How
I'm supposed to do that in Tizen if any cross-application sharing is

Yes it does. I have "groups of users" defined in the Microsoft cloud. I
can specifically define group of people to whom I share a photo for example.
I can do the same with younited, and although I'm not a DropBox user, I

We don't have airplane seatback profile. But for a tablet, TV or car I
can imagine that I would like to have the family photos visible to all
family members instead of having N copies of the same photos under each
In car, driver can administer settings, depending on who's key he is
using (if it's restricted or full access car key). Just like I can
already administer all kinds of other settings.
As an example in Ford parents can set a speed limit and maximum stereo's
volume to teenager's account (key).

Sure, but as long as you cannot have +x for the files you share you
shouldn't have a problem.
If you HTTP GET anything from Web, you are much more likely to hit
viruses than sharing anything between users in/of the same car.
