simple library built on Apple's mDNSResponder for discovering and publishing services using DNS-SD aka ZeroConf aka Rendezvous protocol.

I would like to propose moving kdenonbeta/kdnssd/dnssd (simple library build on Apple's mDNSResponder for discovering and publishing services using DNS-SD aka ZeroConf aka Rendezvous protocol) into kdelibs. Reason: after several months of development I think it is quite good shape and I have several use-cases for that:

• patch for krdc to search for remote desktop. It was approved by maintainer (Tim Jansen) but can't go in without dnssd lib
• patch for kpf to publish information about shared dirs, so you can find it using dnssd:// ioslave on kde, nautilus on gnome or safari on mac
• patch for kaddprintwizard (in progress) - this is main reason why lib needs to be in kdelibs and not kdenetwork.
• random idea I just got (not even started yet) for easy launching remote apps (not whole session): add new submenu to standard k-menu: 'K -> Remote application -> (list of hosts) -> (normal k-menu for every host) '. List of hosts could be populated by searching for _remoteapps._tcp (advertising location of /usr/share/applications and ssh port) or something similar. List of applications could be populated by reading fish://user@host/usr/share/applications and parsing just like local menu, but any 'exec=app' would be changed into 'exec=kdessh -X user@host app' (kdessh would have to be able to enable X11 forwarding)

DNS-SD lib is based on Apple's mDNSResponder, (all functions will return immediate failure when compiled without it) so it would be new optional dependency. If you are concerned about legal issues, then I can say there is nothing to worry about: client library has been relicensed to BSD about 2 months ago. I have provided some patches for Posix version of mDNSResponder to implement missing features (see http://lists.apple.com/archives/rendezvous-dev/2004/Nov/msg00055.html and followups) and according to Marc Krochmal from Apple they are going into CVS today, and after my confirmation that everything is working as expected new release will be made.
