Yes that's the point. IP in UDP is more supported. It has much an
easier way when your traffic travels over the Internet, and maybe you
have to pass some NAT. Some NAT will not handle at all IP in IP
packets.

IP in IP has of course less overhead but you can experience problems
and many network setups. This is why at Freifunk we are thinking of
developing this kernel module.
