I looked closer at the uTorrent program, and it appears that each individual torrent can have DHT enabled or disabled. But because I have the program settings set to disable DHT, these individual boxes are greyed out and unchangeable. So it appears that you could enable DHT for the program, then selectively disable DHT per each torrent as you see fit. That way you could enable it for a 'banned' torrent, or one that you don't care if other (non-tracker members) people can access.

Cheers for all the info, everyone.
