The webui is currently the poor cousin of the OBS parts even though it's wildly used. It's a pain in the ass to code for it
as there is not a API for most things you need to do - and if there is it's cumbersome to use.
OBS source services can currenlty run on the developer workstation and some of them also on the OBS server side.
The goal of this project is to allow everybody running source services as part of their build job. Therefore we will introduce a new "buildtime" mode. The OBS server will pull in the needed service packages and run them before calling rpmbuild or friends.
We have some internal systems for videoconferencing like Big Blue Button or OpenMeetings. But in my experience none of them can compare to Google Hangouts, which is still the best free (as in free beer) alternative for videoconferencing with integrated screen sharing.
While implementing an alternative to Sqwiggle on previous hackweek, I discovered Janus, a lightweight WebRTC gateway that proved to be a quite capable tool to implement video applications.
