I too have missed this feature (from the BSDs ping). Also I needed
adhoc tracking of multiple hosts. So I experimented with libevent2 and
some code from the BSD ping...

You can see the result here http://hoth.dk/xping/screenshot.jpeg

I used the transmit interval for timeout. There's propably a lot of
corner cases I haven't thought about, but it works fairly well.
