Is it possible to run more than one Battle.Net game at the same time on different PCs?

I already own Starcraft 2 and, therefore, a Battle.Net account. But I'm not playing it very often, so I let a friend of mine use it.

If I buy Diablo 3 (which I intend to do) and bind it to this very same Battle.Net account, will we be able, my friend an I, to run these two games at the same time on different computers? Or should I create another Battle.Net account and prey for Blizzard to leave me the hell alone and not asking for an official identification on the rare occasions I connect to the two different Battle.Net accounts with the same IP?

You can log into Starcraft 2, Diablo III, and all 8 of your World of Warcraft accounts at the sametime if you wanted at.

Of course sharing your account with your friend is a horrible idea, him knowing your password means he can access your account anytime he wants, I suggest logging in for him.

Sharing your account of course is against the Terms of Service.

There is no reason to do this.

Solution 2:

Account sharing is a violation of the Battle.Net Terms of Use. It could be that this rule is not strictly enforced by Blizzard but I have already heard cases of WoW user accounts banned for this reason.

Therefore I would suggest you to avoid this kind of behavior. Telling your friend to make his own account and buy Starcraft or creating a new account just for Diablo 3 is a your decision.
