how embarrassing. i've integrated the patches for these above.
they'll be in the next release (7.1.4).

this one is kinda tricky. in the simple case, there would be one
conserver host and when you asked it to shut down it would prompt for a
password only if necessary. the difficulty case is when you have
multiple conserver hosts in a distributed setup. if you put the burden
on the server to ask for a password (and you weren't coming in from a
trusted host) you'd get N password prompts. with the current code, you
only get asked once. but, that too could be an issue...if your
conserver hosts have different root passwords, only those with the same
password would shut down.

so, what's the right answer? i'm not sure. i was thinking that a '-n'
(picking a random letter) flag or something on the client side might be
useful. if you run with '-n', no password queries are done - it just
uses an empty string. that way, you could do a 'console -q -n' and it
wouldn't hang waiting for input. in a similar way, connecting to a
console via 'console -n <console>' would assume an empty password (if
it needed one). hmmm...maybe '-E' for "empty password".

any opinions out there?
