clez.net and serversniff.net are starting to team up some services.
clemens from clez.net proposed an API for services like traceroute or ping. If everything works out you'll be able to fire up traceroutes from different locations on both of our sites, maybe from even more sites round the world at some stage.
maybe you want to participate? - we are open for anyone who is willing to share services like traceroute or ping - all you need is a host where you are able to install an run software like hping, tcptraceroute etc.
drop us a note if you're interested: firstname.lastname@example.org
