We really wanted to like screenhero at SocialWeaver. We spent a couple of weeks using it for our standup calls and development sessions. Unfortunately, we experienced a lot of issues with it. Often times the screen becomes blurry or there's too much echo that would render the whole thing unusable. We will definitely revisit Screenhero in the future, but for now I am afraid that even Skype is more reliable.
Screenhero was amazing for our development team which was based in two different offices (San Francisco and Saint Louis). We leveraged Screenhero for code reviews, pair programming and debugging particularly thorny issues. We were huge fans of the service!
