More then one offline shop on Signature

Hi, they changed the rule on the server that you can now only have one offline shop and one live client charr. I guess it makes sense so it's not just shosp everywhere but what I also loce about this game is playing with the market. They said that if you .offline the second shop one will automaticaly close. Is there a way to have more then just one offline shop? Idk what triggers the account to close, is it internet IP or is it my PC? If I put a client on my wifes PC will I be able to make one more shop? Would like an answer here first if it eill work before i put anything on her PC.
