I built something like this for Shopify. Than Facebook sorta copied my idea with this storefront news. Anyway, I think this niche is very small and your better going for lower hanging fruit then starting with a live stream for software products. There have been businesses like this that were great like criticue.com but surprisingly they went under due to lack of interest and adoption. I personally really liked the service. It was better then a livestream, it was a group of software reviewers giving you feedback.
