Cool.

Assar once wrote a patch that pinged all servers. This should be inproved
with pinging only servers that actually have a outstanding callbacks.

Never though about the TTL thing. It might be harder to add that thing to
rx in a clean way. 
 
I've added a contribtions section to the arla webpage where I mention
