I think this is currently the biggest hole in IPV6 adoption. We need a drop
in firewall appliance along the lines of IPCOP for IPV6. This type of closed
unless tinkered with protection would encourage people to try it out and not
be too scared to move forward. This is a huge opportunity for some
Company/Open Source Developers Group to grab a huge chucnk of an emerging
market...   hint hint :)
