I don't think "will almost certainly be subject to a search list" is accurate, though I do think "may be subject to a search list" is reasonable. > 3.

Strongly disagree. That would leave users without a protocol-independent way of unambiguously specifying "this is a fully-qualified domain name". The practice of applying search lists to names with "."s in them needs to die. Keith
