There's pure java DNS-SD implementation that also includes Multicast
DNS, just like the Bonjour Library, I don't yet know if it supports
DNSSEC, which I believe is important.
While I think link local ip addresses are interesting and may be useful
for large mobile plant (eg a Dragline , Shovel or Bucket Wheel) to have
a backup in case of DHCP failure, it really is a low level OS function
and not our concern.
Here's the site:
http://code.google.com/p/waiter/
Waiter as a Java DNS library replacement
The core of /waiter/ is a clean, modern Java DNS library which can be
used explicitly instead of the very weak services in the JDK. It be can
be used with or without caching, and provides access to far more of the
DNS messages, allowing Java programmers to truly leverage DNS in service
clusters and distributed systems.
Cheers,
Peter.

When we have several reggies running on the internet, it would be

Sim, I hear you when you say you'd just prefer to code it in Java, has
anyone any experience with dnsjava? Their website is so simple, I
decided to attach it at the end of this message, however it is
available at http://www.dnsjava.org/
When I think about a GlobalLookupService, I want something that can co
exist with Reggie.
Daniel emailed me to let me know he's passed on my request to add the
service ID and group set record keys to the Jini DNS SRV Service Type.
The Bonjour daemon, supports Multicast DNS Service Discovery as well
as Unicast DNS-SD, however it is coded in C.
Support for link local ip addresses, is really a low level operating
system function, it doesn't ship with the Bonjour daemon, however OS's
will probably pick this up in future.
I'd recommend anybody interested pick up a copy of "Zero Configuration
Networking" by Stuart Cheshire & Daniel H. Steinberg.
In fact I'll personally purchase and send a copy to anyone ready to
give me a hand to create a GlobalLookupService.
Cheers,
Peter.
