Over at Scienceroll.com – a blog written by a medical student about Web 2.0 and its impact on genetics and medicine – the author draws attention to America’s Army and Forterra Systems as great examples of virtual world training environments for the medical community.

The next wave will be open source platforms such as those I’ve covered previously like Sollipsis, the Open Life Grid and Ogoglio, among others.
