Wake for network access without Bonjour Sleep Proxy? Is there a way to set some kind of "wake for network access" behaviour on my Mac without using a Bonjour Sleep Proxy?

I have a Mac with OS X 10.8.5, but no Apple TV nor Time Capsule or other stuff. I am happy with Unix solutions that require a bit of install and tuning on my laptops.
Wake on Lan works great on Macs with the following configuration : 


Connected using an Ethernet cable. 
Port forwarding if you're behind a NAT Router. 
Enable wake on network access
A sleepy Mac (not Shutdown, it has to be on sleep)


That's it !
