Except you'd have to add a kernel interface just to send ICMP echo  
requests, along with whatever options you want to allow non-root  
users to specify. IMHO that is at least as crazy as a setuid program  
with the same purpose.

Even a general interface to send ICMP packets  is much too dangerous  
-- send out a few HOST UNREACHABLEs with the local router's address  
and you'll knock the whole subnet offline. That's one of the reasons  
there's not an interface to create ICMP packets in the first place,  
for root or anyone else.
