I would very much like to see this ability added at some point. It doesn't matter if it is a bit complicated to set up (even "by just calling Microsoft support" as suggested would be fine), as long as it works once set up. I work in a biggish corporation that hasn't adopted O365 and SharePoint Online yet fully, so my team has set up a "shadow team site" and bought our own subscription that we use. However, since the rest of the corporation is lagging behind without O365, we are constantly signing in and out of services! We sign in to our workstation with the corporate account, and the ability to jump between different O365 sites/apps would ease the team's daily work humongously! Also, I didn't yet mention, but our Customers also use O365 and they've of course setup their own O365 sites with their own AD accounts and given us access via a new AD account with the prefix "external", so a team member in my team might have to use 1 corporate account, 1 team account, 0-4 customer accounts daily, and every freaking time needs to sign out and in and it soon becomes a chaos that counters any possible benefits that O365 might otherwise have to offer - and thus, people fall back to the "traditional" work methods, and send those 10 megabyte Word attachments and Powerpoints in legacy email apps, and stop using O365 because of the pain of overhead work is just too much.
