mmhh, the hna announcments are written into another routing table, have
you checked that ?

This is a bad idea in my opinion. A routing protocol has one purpose
which is routing, not flooding 99% useless information just because it
COULD.

i think the right approch for service discovery is using something like
dns for example. dns is very small overheaded, allows great redundancy,
works on demand...

using TXT and SRV records, a good dns infrastructure and user frontend,
it should be easy to publish services.

here in leipzig we already layed the ground stones for a widespanning,
redundant dns network using anycast ips for redundancy.
