My 2d worth, disabling Ping doesn't make the machine much harder to 
find, and it makes diagnosing problems much harder - in other words, 
IMHO speaking as a networking guy that regularly has to diagnose 
problems AND as a sysadmin, disabling Ping does at least as much harm 
as it does good.

YMMV, that's my opinion.
