Christian,

RFC1070 defines much of what you suggested (except parts of #4). However,
the intended use of RFC1070 is for experimenting. Our solution to #5
was to use ES-IS (Internet-wide multicast). This clearly does not scale!
The IETF-OSI WG is working on a "production" version of 1070 that would
include some kind of routing protocol to run between the encapsulation-
gateways.
