I call BS; $10 says they won't exist by summer. Initiatives like this are usually announced when it's time to cut costs. While a virtual office can be a wonderful thing, it imposes significant problems too: how are you going to train new hires? existing issues can perhaps be handled by teleconferencing, but do you really want to have brainstorming sessions and involved discussions about future strategy via IM (or whatever)? How do you keep your contributors from thinking to themselves 'I'm practically freelance anyway' or handle the work-life balance issues?
I'm not saying it can't work - I've been an enthusiast and advocate for telecommuting ever since I got a modem. But it's not a panacea, and it doesn't work in every employment context. Color me very skeptical.
