@zatnosk @gargron @strypey @fla @mike @banjofox As far as doing multiple protocols within postActiv, they're just modules.  You can enable one or more and that's the language your instance speaks.  Right now postActiv just has OStatus.  I have an experimental Diaspora module but it's not tested well enough I'd feel comfy putting it in production.  I know someone is working on something for the Friendica thing too.
