proven, no. successfully modeled, yes. john heidemann's team at USC/ISI
published as follows:
i quibbled with any interpretation of this work that would cause an
unsignaled/unnegotiated alteration to the way TCP/53 is used, but that
no longer seems to be on the table. the math itself checks out, in terms
of what modern servers and kernels can do. so in my view, if "T-DNS" as
they were calling it becomes an optional first-priority transport, then
large server operators (root and TLD for example) can easily make it happen.
