[tahoe-dev] same origin

[James A. Donald]

Some time ago, someone proposed a local service that would map all 
domains of the form *.tahoe-stuff to the same network address, thereby 
allowing every web page to have a separate origin, thus preventing 
common origin attacks, but this would create some other insecurity.

I did not understand why this would create some other insecurity, but 
failed to pipe up at the time.

But the more I think about it, the less I can see how it would create 
some other insecurity.
