Wow, where did you read that. This was news to me anyway.

Assuming the above is correct, sure. 

An alternative could
be to use the tun/tap driver found in jungerl, that could
sureley be used to introduce raw IP packets on the network.
To read the packet, you'd have to setup your routes i  such
a way so that return packets find their way up to userspace.
