It’s easy enough to see machines that are on your segment of the network, and browse through any files they might be sharing. But these days machines do a lot more than simple file sharing. There’s no way, though, to tell at a glance if a machine is running ssh, sharing out its iPhoto library, or something similar.

If there are Macs on your network, you can use Flame to quickly suss out and display the services running on the machines in your VLAN. It’s still under development, but it still seems pretty handy. Enjoy.
