Anyone using the Spread3d Review plugin/site? Looks like you can share your Sketchup designs with a customer or team and have discussion on the design. Would be useful for hammering out details or even just doing presentations.
I've done a couple of presentations just sharing my screen using Team Viewer, which is free to use, but users have to install their app. It would be nice to have one that just ran on a given web page, though I think the users may have to sign into google still.
