Comment on: Chances of getting this in Docker

@tanzimabir Currently with the admin area I built (#2) it's probably not too difficult to flesh out to have different boards based on giving each a specific url. `e.g. /screen-1, /screen-2` etc. The PR also includes a RESTful system for sending messages to boards, as such we could adapt this to allow specifying the screen name so you can send to specific boards. If my PR gets accepted I'm happy to adapt it to add these features as I think they would be useful.
