Bad description by me. I'll try again.

If I have two PCs in my home, connected with GE to a L2 switch and I buy 10 
Mbit Internet access, I don't want traffic between my two PCs to be exchanged 
through the default route.

They could possible communicate directly using link-local, but I'm not sure 
how they would find each other?

Default gw could send a redirect...
