Personal first impressions: - Any tool that allows for the automatic configuration of devices wrt their routes, is also a tool for a DOS attack. You notice this, and that it should only run in 'trust relationships’. That’s good, but at the moment, the internet has scarce support for trust relationships.
- Negotiation usually implies multiple messages in a tight, ordered sequence. This doesn’t necessarily do well on unstable, mobile networks where messages may get lost, requiring time-consuming re-negotiation. - When you say ‘XML’, I say: needless complexity that runs afoul of what most small devices can or should have to handle. You notice this too, fortunately. Only too glad you didn’t go for TCP ;-) - I wonder about using multicast. Doesn’t that create a chicken-and-egg problem (as the multicast configuration may be part of what we’re trying to configure about a router)? Also: packet storms.
