[Live-devel] GroupsockHelper.cpp and weird problems with long startuptimes for applications

[Ross Finlayson]

I've found that the existing approach - send a multicast packet, 
receive it, and look at the source address - is the most reliable 
way, for most people's systems, to find their source address.  If 
that fails, we try calling gethostname()+gethostbyname().  The 
combination of those two methods seems to work for most people. 
(Remember also that we want code that will work on Windoze systems as 
well as Unix.)

Those rare people who have weird systems for which this doesn't work 
are welcome to write their own implementation, of course.
