A couple other users promised to support the seeding, but we worked out the math and are comfortable that we have enough bandwidth without any external help. And the seedboxes are all spread out with different services and geographically to avoid single points of failure. And even if they do all go down, armory will detect slow downloading and revert to using regular P2P.
I hardcoded max upload speed and upload connections to zero. Further, the torrent engine shuts down after it's done and doesn't even start if it detects a built Bitcoin core database. Lastly, if you still don't want it, you can run with --disable-torrent to not even try. I think I added a settings option, too.
And if you're really scared for whatever reason, you can actually remove the entire BitTornado directory and Armory will run fine with out it. It will simply let Bitcoin core download over P2P.
As you can probably tell, I was pretty careful to cover all our bases :-)
