Google Wave can create a beautiful sea full of interconnected waves if Google can manage to "replace email" and change the "user behavior; potentially this may have a big impact the way we communicate and collaborate.
In terms of scientific collaboration and authoring tools (collaborative authoring) /peer review process this can have very interesting and useful applications. GW comes with open APIs too. As STM publishers we need change to get in this new sea of waves and be in the same wavelength with our users who will adapt this new wave of communication.
