why not just have a "change address" option that takes an old address, a
new address (and optionally a new password) and then does an unsubscribe
and a subscribe?  do not wait for the unsubscribe to succeed before 
doing the new subscribe.  whether or not confirmation happens will depend
on the existing subscription confirmation setting for the list.

for that matter, what advantage does a "change address" function have over
simply unsubscribing and re-subscribing?

the only problem i can see is that if the old address is 'dead' then the
unsubscribe can not be confirmed.  so be it.  leave it alone and it
becomes like any other 'dead' address in a list.  what does mailman
normally do with addresses that are consistenly undeliverable?

this is exactly why subscription confirmation is used.  this should only
be possible if you have disabled confirmation.

the unwilling user should also get a subscription confirmation request and
the subscription will not take place until they confirm.
