@lanodan@loadaverage.org AFAIK GNU Social doesn't have anything like "Streaming API" for client applications. Recently @kromonos@social.bka.li started implementation of "Push notifications", but it's also not done yet from a server side, see
https://github.com/andstatus/andstatus/issues/231 There will be not much work to implement this at the #AndStatus side once it works on a server.
Your help is needed here...
