I just saw the video, looks awesome. I have experience working on conferencing products and UberConference looks pretty sleek. Some of the pain points that they mention in the video are real. There are plenty of conference applications/products to choose from and not sure how UberConference is going to standout. Also some of the features supported by UberConfernce can be added to the existing conference application with some effort. Its not impossible to add these features as mentioned by craig in the video. Its a crowded market with big potential. All that said, Wish these guys great success.
