For the 99nicu Meetup, not only the venue but also the budget is down-sized So, there won't be funding for the kind of web cast we originally planned.
Instead we plan to use Periscope, the live streaming service that (I think) is a Twitter-owned service.
It seems from the Periscope test run below, that the image quality from using a smartphone is not superb (despite having the latest model!) but if you plan coming to the 99nicu Meetup and are experienced with Periscope Producer, please drop me a PM or an email.
