So Leah, that seems to be a new problem; not sure how much AC has heard about it, but people here are just starting to report it. Now it is likely that more and more people will likely notice it, and hopefully a fix or work-around will appear.
Your question about your set-up is separate, and you will probably get different answers. If all of your machines are in one location, I think your P2P network is probably fine. Others will likely feel differently and will tell you so.
