Allowing all sites access

[Andrew Ducker]

I've been trying to work out a reason I wouldn't allow any site to 
verify that http://andrewducker.livejournal.com/data/foaf is me - they 
can't think to check that address unless I type it in, and if they do, 
all it can check is that I'm also logged in as that user on that site.

That being the case, will it be possible to state that I'd like to 
authorise all sites to verify my identity, rather than authorise them 
one at a time?
