[ejabberd] Ejabberd hardware requirements for very high load

Hi all,

I've read the two whatsapp blog articles, and I'm very interested:

1. They mentioned Erlang. That means they're using ejabberd?
2. Since scaling ejabberd is just a matter of adding nodes, what exactly 
is the work needed to do in order to scale to the whatsapp scale? (yes I 
don't have much idea on the clustering thing)

Rgds,
David
