Request: Ability to log on from multiple locations

I don't know if this is viable, but I for one would greatly appreciate the ability to stay logged on from more than the current number of locations.  Ideally for my selfish needs it'd be awesome for that number to be four (laptop, phone, PC, other PC) with maybe a check-box on the log-in page with "log out from other locations" (thus allowing for people who were just browsing on a friend's PC), but even three would be super.

This probably is not an important feature, but it'd sure make it easier to use the ever-excellent Deckbox on my phone without needing to re-login all the time.

Thanks for the consideration. =]
