I am thinking of a different approach, where if you build with IPV6 support enabled, the stack has support and additional member functions for both IPV4 and IPV6, rather than having different IPV6 top level templates...I have started experimenting with this approach.

The CCXX_IPV6 wrapped classes seem a practical and quick fix. I can't
think of a simpler way of fixing this problem. I agree it looks a bit
ugly, but it seems the best short term solution. We should think of
a tidier solution for the future :)

Maybe IP addresses should be handled in a different way in ccRTP, or
maybe a common base class for both IPv4 and IPv6 addresses could be
added to CommonC++.

When I look into the case of OutgoingDataQueue, I was thinking maybe in
that particular case, we can have a CCXX_IPV6 wrapped
OutgoingDataQueueIPV6 which inherits from the existing
OutgoingDataQueue.  It could re-implement just those methods that deal
with addresses with new methods that use the IPV6Host objects, cap the
v4 virtual with a dummy method, and offer a new v6 virtual of it's own.
  We could then feed OutgoingDataQueueIPV6 to the upper level template.
  That might be ugly, but it could work without breaking a lot of
existing code or writing all that much new code.  The same could
probably be done for the other two classes.

I would like to see some feedback on this before doing this :).
