Hm. I think this is worth a separate thesis. ;-) (extraction of
locations from DNS, managing databases of addresses, arranging `good
looking' graphs, ...)

I converted those two maps to gif and put links on my page. BTW,
probably, tkined may compile cleanly on your Mac. Juergen? ;-)

Real automated map generation is quite difficult, I think. It would
take much time to define all needed attributes and write some code.
Once, reaching the point of acceptable operation, the 6bone might be
that large, that it doesn't fit on one page. ;-)

Nice aspect. ;-) But I don't want to put much work on arranging those
maps. For me, using tkined is just a very nice way to combine the
creation of map overviews and some kind of network management.

Probably we could put another field into the registry records, that
contains a tkined map URL. Such a map may contain pointers to
neighboring tkined maps. This would be a good way to decentralize the
map management, although it doesn't give an overview at once.
