IPv6

[Lance Spitzner <lance () honeynet org>]

Recently one of the Honeynet Project's Solaris Honeynets was compromised.
What made this attack unique was IPv6 tunneling was enabled on the system,
with communications being forwarded to another country.  The attack and
communications were captured using Snort, however the data could not be
decoded due to the IPv6 encapsulation.

This made me consider, this activity could be used as a means of
"covert" communications or activity.  Many IDS systems, and potentially
many sniffers, have difficulty decoding IPv6 activity.  Was wondering if 
others had seen this activity, and the implications it may have to the IDS 
community?
