I use XBMC, and make use of profiles for; myself, the wife, and the children.
I would like the ability in trakt to create a family account, so we can all still have separate libraries and use different accounts to scrobble. However via the family account they are linked, so there is an overview of what we have all watched etc recently.
Also, possibly the ability when viewing a family members activity to say "I watched this with them too" and have it show up in your feed as well. Or a popup in XBMC much like the rating dialog, which would have the same effect.
What if you could have your collection sync between accounts as well?
Is there a solution to this yet, as I am also curious

I would like something similar but go about it in another way.
I was thinking the ability to link accounts with some sort of process. Then the ability to chose which shows should be scrobbled/rate on both accounts and no matter which account is being used in xbmc, the update would be reflected on both account. You could choose all shows or movies or individual selection. This method wouldnt require a modification of the Addons since your still only using 1 account to scrobble.
