That's quite logical : SSM is 5 years old (counting from the first 1999 
Express SIGCOMM paper) compared with ASM which is almost 20 years old 
(counting from the first SIGCOMM
host group model definition from Deering in 1985). But SSM could grow 
faster, as it rely on the same routing routing architecture than ASM ;)

For information, at the time of writing, linux is the only operating 
system supporting IPv4/IPv6 SSM
natively (first patch starting from 21 may 2003 are now included in the 
main kernel).
