I strongly disagree. I think the standard makes it clear that Bcc recipients are 
not supposed to see one another. They are supposed to be secret and concealed.

The RFC says "The "Bcc:" field (where the "Bcc" means "Blind Carbon Copy") 
contains addresses of recipients of the message whose addresses are not to be 
revealed to other recipients of the message."

 From this we can conclude 1) the addresses in the BCC field are recipients, and 
2) their addresses are not to be revealed to other recipients.

 From this it logically follows that addresses in the BCC field are not to be 
revealed to other addresses in the BCC field.

I'm sure that is not true. It nowhere says that limitation anywhere in the RFC. 
BCC recipients are supposed to be private, not disclosed to others.
