Ever wonder what Rendezvous… I mean Bonjour services are available on your network? Browsejour will tell you quick. It’ll tell you the services available, which machines over it, and a quick explanation of the service itself. I used to use Bonjour Browser, but it doesn’t offer service descriptions and the interface wasn’t quite as pretty.
One nice thing about Bonjour Browser is that it displays the IP address, not the MAC address. I do like the interface of Browsejour, it is very promising.
