Biodiesel is currently intended to be blended at the pipeline terminal. The biodiesel tank and piping does need to be heat traced, however when blended to up to 20% biodiesel, waxing at cold temperatures so far does not seem to be a problem.
Another upside with biodiesel (including blends) is better lubricity than straight petro-diesel.

Yes, I've heard that. If I'm not mistaken, I've heard it really cleans better than petrodiesel.
