Bullshit.
It is impossible to transmit every single order by Mutum Sigillum to Mtgox in Japan on behalf of their clients, because wire costs would kill the buisness. The two companies were merly reducing funds imbalance from time to time - it cannot be called transmitting money on behalf of their clients. And Mtgox is out of U.S jurisdiction, so unlicenced money exchange part does not apply as well.
I think we are dealing with political attack.
And so the shitstorm begins!
Yes, we do know the people behind the Coinlab lawsuit has deep pockets, also with political connections. So they could pull this off.
