iTunes Home Sharing: 2 Countries

[PCFan]

I live in the US right now. Let's pretend I moved to Canada and have a Canadian iTunes account for the rest of the post. Can I set iTunes Home Sharing to use 2 accounts simultaneously, one for the US account and one for the Canadian account so that all movies from purchases from each account can be combined in a single library? I understand that this can't be done if streaming from the cloud but I'm not sure if it applies to Home Sharing as well. Would I have to log out of my US account and log into my Canadian account if I wanted to access movies purchased from the Canadian account if Home Sharing as well?
