I am glad you like it :)

There's good news and bad news.
The good news is that a traceroute feature is soon coming along as a  
part of
another SoC project. You're welcome to beta test it, for more  
information
read Eddie Bell's anouncement.

The bad news is that currently raw sockets aren't planned for NSE for  
one
very pragmatic reason: the nmap nsock library does not provide a raw  
sockets
API. Adding raw sockets to NSE would require to either extend the
nsock library or to come up with a separate implementation for raw  
socket I/O. In both
cases the task is a project which goes beyond the effort of adding a  
nifty feature.

If NSE finds resonance I will definitely keep the raw sockets topic  
on my
TODO list. As a matter of fact LUA users in general are complaining  
about
the lack of a LUA raw sockets library so I am sure there is interest  
present.

Thanks for the testing.
