But what is jigdo-bd? Under what conditions is it the proper choice?
"bd" must be mnemonic for something, but I don't make the connection
the way I do for "cd".


  "bd" stands for Bluray-Disc.



You might want it if you have a bluray drive for some reason. I haven't seen a regular PC with a BD drive yet, so I assume they are fairly rare in the wild. Reader/Writer drives (in the same form- factor as standard PC 5.25-inch internal CD/DVD drives) seem to be selling for about US$100 - $200 on the web.

At <http://en.wikipedia.org/wiki/Blu-ray_Disc_recordable> is the following information:

"Blu-ray Disc recordable (or BD-R) refers to two direct to disc optical disc recording technologies that can be recorded on to an optical disc with an optical disc recorder. BD-R discs can be written to once, whereas BD-RE (Blu-ray Disc Rewritable) can be erased and re- recorded multiple times. Disc capacities are 25 GB (23.28 GiB) for single-layer discs, 50 GB (46.57 GiB) for double-layer discs, 100 GB for triple-layer discs, and 128 GB for quad-layer discs."

25GB is about 5 single-layer DVDs. So you can get a substantial fraction of the entire Debian distribution, including source, on a single BD disk.
