It can be setup as an email server, office programs, etc, accessed both locally and remotely. Aside from the security & privacy benefits, web developers will love the full web IDE. This looks like real competition to Windows Azure. On their site they claim that "cloud computing is little more than a marketing buzzword, used to dress up the cold ugly business model of renting software, with the additional cost of losing your rights and abilities to fully protect and control your data, all in exchange for the convenience of a web based application. In reality, the entire cloud computing business model revolves around vendor lock-in, through proprietary and closed source software that is either ad supported, subscription based, and/or profits from the sale of your personal information... Instead of complaining about these problems, we've simply done our best to correct them." Their solution, GroundOS, appears to be a combination of installing a LAMP server to host the cloud from home or on a web host, with a PHP/Ajax framework that "provides a full portable IDE" and desktop like experience. There's a lot of text, but not a lot of screenshots or information is given, other than the first public beta will be released on May 1st. Is this an open source response to Windows Azure?"
