Box 1: Has the DVD burner
Box 2: Has the data

I want to do this:

Box 2 (data) ---> Box 1 (DVD burner)

The data would transfer through the crossover cable.

So, how do I accomplish all of this?

I imagine one possibility is to have the drive in Box 2 into a network drive. And somehow, Box 1 would see it as a drive that it could burn data from. I'm thinking I'd have Box 1 mount it as a drive. Afterwards, some growisofs command that transfers data from /mnt/ntwkbox2/home/ozar/passwords/ /mnt/hdc would be employed. I'm not too sure how to go about this.
