facebook - if user liked page without user permmision
===

Ok, a want to find out if guest liked my facebook fan page without loging in with facebook and getting permmisiion. 

All i have to do is:

1) getting user id of guest (how to do it without logging in?)
2) use fbl - SELECT uid FROM page_fan WHERE uid = UID and page_id = PAGEID

   which will tell me if guest is user

3) send access token of administrator of page with fbl (how to get acces token of specific user)?
