The Wall Street Journal's Emily Steel mentioned Eyejot in her article Video Gets Entrée Into Email which was posted live today. The article primarily focused on Goodmail's recently announced product aimed at helping publishers get video players successfully placed and operational inside email messages.
This has long been a challenge for web-based email platforms. They have, for security and control reasons, intentionally stripped out HTML embed and object code, which is required to, for example, host a Flash player (or more nefarious playloads). So, the industry has reacted by either embedding static images that look like they're part of a movie and invite the reader to "click to view" or, more creatively, have utilized animated GIF images to expose some motion in the hopes of guaranteeing a "click to view."
The Goodmail solution is certainly interesting but it's primarily an agreement they've established with only a few ISPs. So their solution isn't universal. For us that's a problem. While it might be really cool to play video inside of an email message, unless it's a solution that can be used all the time, everywhere, it may ultimately be less effective than more traditional techniques.
Incidentally, Eyejot intends to offer an animated GIF option for its notification messages to PRO Plus members in the near future.
