To evaluate this comparison you have to look at the equivalent 
situations. The Emailing of a multi-recipient Fax Message is most 
closely equivalent to using Fax Machine that has an Address book that 
can assign a delivery list to an entry (IOW: Select this entry and it 
will dial each phone number in order and deliver a copy of the fax) 
and will read and cache/buffer the full fax into memory so it can 
send from the memory instead of reading/feeding the pages in real 
time [as it is transmitting]. Yes - it will negotiate the content 
(Speed/Resolution) separately for each connection but then that is 
what is supported to be happening with a multi-recipient Fax Message.
