If nobody tells us for a year or two then zap. Given that we're in the process of implementing the v2 interface, I don't think it'd be wise to perturb v1 interface at this point. We're gonna have to carry around v1 code for quite some time anyway and I don't think carrying the tcp code would make whole lot of difference given that the code is likely to stay static from now on. Thanks. -- tejun
