OpenSLP 0.6.7 now includes support for the following:
--------------------------------------
Minimal DA support in libslp. Apps linked with libslp will talk to DAs if the net.slp.DAAddresses property is set in the host's slp.conf file.
Broadcast is supported. Set the net.slp.isBroadcastOnly = true in the host's slp.conf file.
Full DA support, dynamic DA discovery and DA functionality for slpd (ability to propagate registrations to DAs) is scheduled for 0.6.8.
CHANGELOG
