Perhaps I just haven't researched this enough yet, but it seems to me that I'd rather spend the $$$ on a little bit more stuff to have in the shop to make biodiesel and not mess with the car at all, than installing a two-tank system in the car, with all the associated fuel heaters, valves, etc.
Thoughts?

Below is my opinion on the subject. My opinion is based on my experience with VO. I have no experience with making or using biodiesel, but I have read a bit on the subject. I don't know everything, but here is what I think:
100% Bio diesel will eat every bit of rubber in your fuel system. So, there is a lot you have to "modify" to run B100 for any length of time.
B100 is toxic. The chemicals used to make B100 are toxic. The chemicals cost money. I read that it costs up to $1/gallon to make B100.
B100 congeals in the 40's F ( I have read ). I can run my 2 tank VO system at -20 F.
Vegetable oil fuel is eatable. With a flash point of over 600 F, it is safe to store and transport. (I don't know the flash point of B100, but diesel is 125 F).
A cold up-flow system for processing vegetable oil can be assembled for less then $100. I do not know how cheap a Bio diesel processing system can be made.
A home made 2 tank system can be installed in a weekend for less then $500.
