But thats a problem with the OS.

If a OS looses the interface where the TCP connection is bound, it  
should signal the applications that those TCP connections are no  
longer valid, right?

FYI, the last time I discussed Pings on a client context scenario, we  
decided on:

  * whitespace pings each 45 seconds (to keep NATs happy);
  * Requirement to have a XMPP ping sent if more than 45 seconds of  
inactivity is detected.

The second point is worded like that because we don't immediately  
send the XMPP ping. We wait 5 minutes or until the user needs it (so  
the next time we send any stanza we also send the ping).
