17GB is easy to download with BitTorrent -- and the protocol handles error checking and correction. You're right to worry about a dropped bit ruining a 17GB download. But with BitTorrent you need not worry.

Since yesterday, I've downloaded the 17GB file, and have in turn uploaded 50+ GB. There are currently 20 of us with our clients waiting for the next person to begin a download. It will max out any one person's download speed as long as we keep seeding.
BitTorrent works very well for this sort of thing. Hats off to Dave for using BitTorrent!

Having watched this long discussion (I have no choice if I'm in the group), I'd just like to mention a few things.
First, 17GB is just too large an image for successful download. Just one bit needs to be lost and the whole thing is barfed. Some web browsers won't do it although they will say it was successful.
Second, I'm sure all this software and the OS image won't use a whole 128GB SD card. If you compressed 128GB down to 17GB that means there is a lot of empty space.
Third, you probably can build all this on a 16 or 32GB card. Compressed 16GB would be less than 2GB. 32 probably less than 4. That would be a much easier download.
If the author doesn't want to rebuild this (I'm sure it is a major task, search the net for procedures on how to reduce the image size.
For those that want to install this on a larger SD card, you just copy the 16GB image to a 128GB card, boot up, and use the Raspbian utility to expand the image to use the full size.
Just my 2 cents after decades of doing this. Your mileage may vary.
