A colleague at work suggested I look at Blue Jeans, a web-based videoconferencing service (similar to Google Hangouts or Vidyo). I had never heard of the service until the suggestion. Blue Jeans looks interesting, and does 80% of what Scopia does (another service we use).
Cost seems to be about $50 per user per month. I don’t know if that would be a floating license. I think the service is worth testing, and will try and find some time to do so. Vidyo, their competitor, had a strong product when I looked at it last, so I am wondering how well it competes (in terms of usability and cost) with VidyoH2O for Google Hangouts.
