Why should it be slightly less than 1500 bytes? 1500 is only the maximum 
size of an IP packet transported on an ethernet network. But an ethernet 
frame is not always 1518 bytes long (including ethernet protocol data). 
This again is only the maximum size.
Ethernet frames can be as small as 64 bytes (= 46 bytes of IPv4 data = 
20 bytes IP header + 20 bytes TCP header + 6 bytes). So it's only 6 
bytes of XMPP data, that is always at least used (or padded).
