Mahalo is a pure Java implementation of mDNS and DNS-SD, based off of the draft-cheshire-dnsext-multicastdns.txt and draft-cheshire-dnsext-dns-sd.txt documents. It has been tested with Apple's Bonjour service and seems to work, though it has not gone through Bonjour certification.

Mahalo is tangentially based off of the JmDNS project.
