Silly Question: D3 and Battlenet Account(s)

[Eloni]

Hey folks,

somehow I got interested in D3 multiboxing after a long long break and retirement from WoW boxing.
I guess I will give it a try! :-)

The only thing what I couldnt figure out yet is:
For 3-4 D3 accounts I need to create separate BNet accounts or not?
In WoW it was all running on the same BNet but its the same for D3?

I tried the search here and even in google I wasnt able to find a clear and sufficient answer.

Thanks a lot!

Greetings
Eloni
