Question regarding Canadian playing online from US

[TheGardener]

My Canadian cousin is going to be in town for a month for work, and he will be staying at our house here in the USA. He has just started playing poker, and mainly plays at Party Poker.

Obviously, my real money Party account has been closed, so I don't play there any more. But will there be a problem with him playing on his party poker account from my home? Do poker sites care and/or track where people are logging in from?

Since he has a small bankroll, He also does some bonus whoring. Would there be a problem with him signing up for a new poker site, which is banned in the USA, from my home computer?

I still play, but only at Full Tilt, Stars, and Doyles. As long as he doesn't log in to one those sites from my computer, we should be ok, right?

Any info would be appreciated. He's here starting next week. I don't want to jepordize either of our bankrolls due to us not knowing what is acceptable.

Thanks
