can My Brother and I play two seperate FTP accounts on same PC?

[Pokerpun]

I am stuck with a non rakeback FTP account so I only play FTP when they give me a bonus. My brother has opened his own account he lives at a different address - if he plans to come round to my place regularily for poker coaching from me while playing on my computer from my address is there any possibility of either of our accounts getting frozen or something?
