Good idea, but there are 4 people in my house, all with their own Google Accounts (Plus one for my Media Centre). We have two printers. At the moment Google only lets you print to your own printers, so three of the Google accounts are unable to print. (Technically 4, as one of the printers is connected to a Linux box, and this is Windows only ATM)

We need printer sharing, Google!
