URL relationship permanence

[meepbear *]

Sorry for the thread hijack but since everyone's debating URLs, could 
someone enlighten me what a consumer is supposed to show as someone's OpenID 
url in the following chain:

http://tinyurl.com/something/ (302-redirect to)
http://mysite.com/ (openid.delegate as)
http://livejournal.com/users/someone (302-redirect to)
http://www.livejournal.com/users/someone/

I'm inclined to pick the second as the user URL and the spec would agree, 
but I think it was more intended for the situation of URL 3 becoming URL 4. 
Everyone realizes that three and four are identical, but that's not going to 
be true for 1 becoming 2.

I'm not advocating picking 1 as the URL, but I would like to know how the 
consumer is supposed to handle it? If it does nothing and the user is 
posting a comment, then they will be wondering why it's showing their domain 
and not the tinyurl as they had intended; or the consumer does an extra 
check and returns an error if the redirection moves to a different domain 
(livejournal.com <-> www.livejournal.com is fine, tinyurl.com -> mysite.com 
is not).
