What does this have to do with ISPs? You mean mess with my dns query packets to my own DNS server that is NOT hosted by them?
Yes, that's what I mean.
Well in that case i ll tunnel my requests.
Sure, you can even put the IPs on your hosts file. But 300bps was talking about the "people" in general switching to OpenNIC - and I think that it's unlikely enough that they'll do that, much less that they'll start tunneling their requests.
