Google will soon start letting Apps users buy additional storage for some of the applications in the hosted collaboration and communication suite. Administrators must also allow use of the Google Checkout payment system in their domains. Users can also apply the storage to photos published in Blogger and Picasa Web Albums, if these two services are part of their Apps domain. There are five options, ranging from 20GB for US$5 per year to 1T byte for $256 per year. The feature is formally called User Managed Storage.”]
