I have built such a gateway for SSH: it accepts the connection, powers on the target machine if needed, then forwards traffic.

The advantage over just catching any packets is that an SSH connection is authorized, so less noisy in terms of undesired wakeups.

Apple has this. It's called Boujour sleep proxy, and it allows a always-on device like a Airport or AppleTV to claim the IP address of a sleeping Mac, waking it with a WoL packet when traffic for that device comes in. It's probably pretty useful, but is annoying on a managed network, as it spams my arpwatch system every time the IP is transferred between devices.
