make 0*Infinity = 0

I'm really stumped on how to make 0*Infinity evaluate to 0.
I've tried all the obvious things, like
 Unprotect[Infinity]; 
 Infinity*0 = 0;
along with all the variations I can think of using UpSet and 
DirectedInfinity[_], etc.
Alas, 0*Infinity always comes back with Indeterminate.

Thanks!
Daniel
