Last I heard, there are Intellectual Property claims with ISATAP, which is why the RFC is not standards track and which makes it effectively a proprietary protocol.
Unless that's been resolved, I think the claim by the IP owner is that it can't be distributed without a license from them. So, maybe not worth the effort for an experimental RFC. +-DLS - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
