Each Glisser LIVE page (glisser.live/yourcode) supports a single stream and a single Glisser code (glsr.it/yourcode), be it a presentation code or an event code. So whilst Glisser LIVE can used with the Glisser event structure, it can only be with a single stream.
What this essentially means is that Glisser LIVE supports single-room events perfectly. Where there is more than one room, Glisser LIVE can only support one stream at a time - although this doesn’t necessarily mean that all streamed presentations need to be from the same room.
