Jon,

Obviously, to merge multiple realms, you need an overlay; that overlay
must provide a routing function; you can do the routing function either
using explicit paths, a la UUCP, or global addresses and computed
routing tables, just like IP. That is exactly what IP was designed for
initially, e.g. merge an Ethernet realm and a packet radio realm. Do
people still say Catenet? Now, how is that different from the
combination of Shipworm/Teredo, 6to4 and other IPv6 transition tools?
