We do offsite installations and upgrades, message sales@nodebb.com
Of course, we do have docs so you should try it yourself just back up everything first!
Edit: to answer your original question, we do plan on building an upgrade button into our hosting plans control panel - right now we just upgrade customers manually. It's probably impossible (or hard) to make an app upgrade itself via acp, we would need to make the acp a standalone application (we've toyed around the idea, but not worth the development time)
temporary fix:
within websockets.js add the following code inside the if(uid) block (inside io.socket.connect):
if(!global.socketlogin) global.socketlogin = {};
global.socketlogin[sessionID] = uid;
then after an ajax call ( app.get ) in webserver.js for example,
global.socketlogin[req.sessionID])
will show if the current user is logged in.
