http://www.liquidhearth.com/forum/hearthstone/457243-running-multiple-instances-of-hearthstone Haven't tested this, but this seems to be the answer for your problem. As for botting with hearthbuddy you can only bot one instance of hearthstone at one time per license, but you can use as many computers as you want just not at the same time. You can purchase multiple licenses if you want to bot multiple accounts at once. Hope this helps.
