> What were you looking for in the branch?

The code that would get the correct source address on server replies.

I don't even know if it is possible.  The current  code turns on the right 
option and then gets the source address when it reads a packet using recvmsg() 
or recvfrom().

Is there a similar option to get the dest address?  Is there an option on send 
to specify the source address?

How much will that slow things down?  Would we be willing to add the extra 
sockets to get that much of a speedup?  How ugly will that code be compared to 
the extra sockets?

Can we rewrite the isc code that does all the work of keeping track of 
interfaces so that it is simpleer/smaller?

If you aren't willing to test your changes on interesting cases, then please don't work on this area.  Yes, the current code is ugly, but there is a reason for that.
