:-)

I was thinking more of "generally within the corporate context" - homenet
is (as you say) much more of a challenge. Within the corporate context I
think the general solution is to make this part of the managed machine
configuration (along with X.509 trust anchors, etc.), i.e. don't specify
the "internal" configuration details in-band, but just give the client
some kind of name for a collection of configuration settings it should
already have.
