I still torrent using horriblesub's rss feed.
I can still go back to use Nyaa (either rss or just to look stuff up), but a single near-monopoly group would be ideal. Auto-downloading every English-subtitled anime from nyaa would just be 70% redundant.

I might sign up to Crunchyroll as long as they don't severely cripple Australian access to titles.

As for size, 20TB storage takes care of that.
