[Live-devel] unicast - porting of Live Medea code to Symbian

If you don't plan to use IP multicast at all in your application(s) (that 
will use the LIVE.COM code), then I don't recommend removing any of the 
existing code.  Instead, just leave the existing multicast support as is, 
but just don't use it.

However, if you really want to remove multicast functionality from the code 
(e.g., because your TCP/IP implementation doesn't define 
"IP_ADD_MEMBERSHIP" or "IP_DROP_MEMBERSHIP"), then you can do this simply 
by modifying the functions
         socketJoinGroup
         socketLeaveGroup
         socketJoinGroupSSM
         socketLeaveGroupSSM
(in "groupsock/GroupsockHelper.cpp") so that they do nothing but return 
'False'.

One other thing you will need to do, however, is change the implementation 
of the "ourSourceAddressForMulticast()" function to (somehow) return the 
computer's own IP address.  (Despite this function's name, it is sometimes 
used even by unicast code.)
