Going a bit further, since I *do* have experience with this: Without using Linux guests, the IPv6 support in VM TCPIP is not sufficient to qualify as usably IPv6-ready unless you are writing *all* your own network applications. If your network is going to IPv6, you will need to use a v6-to-v4 gateway and do mapping from the IPv6 world to the existing applications, or replace them with Linux-based equivalents. The IPV6 support in the Linux TCP stack provides the necessary gateway code. This is Yet Another Reason to use the reference architecture I proposed in my VM:ANI paper -- all the necessary parts can be built into the Linux appliances. I have the necessary guest appliances built to provide usable IPv6 support for CMS users. Contact me offlist to discuss further. -- db
