I'd strongly suggest NOT using broadcast or multicast!  If you receive 
an NTP query, respond with the correct time.

You might announce the availability of your server by posting the 
details here.  NTP.ORG maintains lists publicly available stratum 1 and 
stratum 2 servers.  You might want to ask the your server be listed.

You should probably check the fine print in your contract with your 
internet service provider.  Some providers prohibit their subscribers
from operating a server!
