My bro who services servers for a living said 'I tend to switch pinging off at the router to stop script kiddies finding a live IP they can port scan, there are no effects from switching this setting off.'
Yes, but disabling ping replies on routers does not disable all type of ICMP, just the ones dealing with ICMP Echo.
That's what you'd hope. Without actually testing, I've seen some routers (remotely, so not sure what they were) that ignored ALL ICMP when the owner told me they'd "blocked ping". Including all the useful ones :-/
Apparently, it's quite common for domestic routers to disable all ICMP when ping is disabled.
With the amount of open ports due to msn, yahoo, auto software updates etc, I don't think preventing a router responding to pings gives even the sightest improvement in stealth.

If you're Steve Gibson (of GRC fame) then he thinks disabling ping is important - but then he is in the US - where is very common to NOT use a router at all, and plug your only computer directly into your cable or DSL modem. Which is another thing all together
