    I have heard that there is a third-party version of "traceroute" available
    (third-party traceroute means the ability to find out how a packet travels
    from point A to point B when you are at neither point A nor point B). Is
    this true, and if so, where can I obtain it?

There is a public domain version of traceroute posted on zerkalo.harvard.edu.
I don't know if this is the canonical source.
You should know that this program requires modifying your kernel.
