Assuming it works well, it would have nearly all the same advantages as working in a shared physical office vs working at home. It really depends on the job of course, but for anything that requires any kind of collaboration, working with others in the same shared space for the duration of the work day is quite a bit different than just relying on conference calls and messages. There's a lot of casual interaction that otherwise gets missed if you're relying solely on video software. Also, for managers/employers, they like to be able to monitor and keep tabs on people like they normally would be able to do in a physical office and a shared virtual space would allow them to do that in a way that normal remote communication would not. Also, "company culture" and that sort of bullshit would play into this as well.
