I am trying to troubleshoot a latency issue for some of our networks,
and was wondering about this.Knowing that routing isn't always
symmetrical, is it possible for a traceroute to traverse a different
reverse path, than the path that it took to get there?  .or will it
provide a trace of the path the packet took to reach the destination?  
According to definition, is should take the same path, but are there any
other cases that I should be aware of?

a traceroute shows the outbound route. it's possible for the the probe
packets to follow one path and the returning icmp packets to take another
path. a looking glass in the AS your tracing to is a good way to see what
the return path is...
