Per the current policy in place the Web server FOO.COM is protected by the  
client not allowing a site on BAR.COM to retrieve information from  
FOO.COM. A site on BAR.COM can already issue a GET request to FOO.COM  
using <img>, <script>, etc. This same GET request is used to allow  
cross-site exchange of information through an opt-in policy as defined by  
the draft.

What exactly makes you think this is not possible?

Do you have a more concrete scenario that illustrates this? I'm not sure I  
follow.
