I Currently use trakt.tv which i have to manually sync, rather than having it auto scobble and mark collected or watched as it does with infuse on the ATV2. I also am between to cities and have a identical collection at my GF place, and watch content with her and then back at home. I haven't been able to load the trakt plugin correctly on 1 machine so i have to manually update what i've watched on each machine. The trakt plugin is no longer being supported by the original developer either.
I would love to see either trakt integrated better, much like infuse for apple TV and iPad, or a similar system for one user to 'sync' watched and collected shows and movies on the same account with different locations of content.
