ISATAP is now RFC 4214. It is a key IPv6 transition tool. It is very well supported in Microsoft Windows. ISATAP is implemented in the USAGI kernel extensions. It has been removed from the most recent STABLE version (long story). I am an IPv6 engineer, but not a developer. I would *love* to have ISATAP in the 2.6 Linux kernel. I cannot do the development, but I will be an enthusiastic tester. Can you bump the priority for ISATAP higher on the list? Thanks.
