Under what circumstances are multicast addresses used?

Is it for Network Entity traffic only, or can multicast addresses
be used as SNPA addresses? 

The advantage of using multicast addresses as SNPA addresses being 
that configuration changes would not be required whenever a 
network card is replaced in an ES or IS. A possible problem 
however, if multiple ISs exist on the one LAN, which IS does the 
routing?

If this is simply an implementation issue, does anyone have
any thoughts of pros and cons of whether or not to use multicast
addresses this way?
