Can anyone list the internet apps that depend on TTL or actually look at
from the IP datagram?  

Here are some purely guesses:

traceroute
tcpdump
netstat

I am still wondering also if TCP connects are only depending on the fact
that ICMP time exceeded/datagram dropped or watching the TTL timer?

In all this theory it just dawned on me to check how much pain re
porting apps will be caused by this???

thx
