DNS shouldn't be a hog, but I'm at .5mbits up and about 4 down, so between surfing and voip it should be fine - but I've got a domain that does a couple million dns queries every month. I think it's that one domain.
In any event, I think I found a reasonable solution. Most of my domains don't do enough traffic to worry about, and I was finding it difficult to find a dns service in my country that would allow me to host all the dozens/hundreds of domains I have (or at least host the dns for them). I eventually found a company that does do it, and just moved over my one domain that's problematic. That'll take 95% of the load off my home connection, and that should fix it I think.
It's not pretty, but it works :).
