The typical way to do this is have some sort of remote_ping method that returns immediately on the server (or on the client) that the client (or the server) calls every once in a while, with a timeout for the response. If that times out the problem is likely the connection, not the server being slow, in which case you can close the connection.
Yes, it's the same thing as making a pseudo "timeout" with a callLater.
Not exactly. What I'm suggesting is a different command that you send in addition to your regular operations. This extra command, "ping", is expected to return a result quickly; if it doesn't you know something is wrong. That way even if your regular commands take a really long time for the server to process you can still tell if the server itself (or your connection to it) is ok. Every 10 seconds, say, you ping the server; if you don't get a response back in 5 seconds it's probably down.
