I guess that having this come from a software guy is a bit weird, but it is still true. In regards to the visual communications industry, it applies even more. We’ve just released our BEEHD product, which allows others to build and manufacture hardware based videophones. We’ve also just announced our partnership with Samsung, together creating

In other words, why is today different than the past? A (very) early demo of our new BEEHD solution. (more details here) It all boils down to the list of barriers to video calling that I have listed here in the past: Bandwidth Processing power Latency
