> One other catch is that your ISP might block you for not using their DNS; BT (UK ISP) did this Erm ... what? How does that work? If they don't see DNS reques

  What happened is going online resulted in everything being redirected to a BT page saying you're not using our DNS and to change settings so you do. Some googling revealed a few people who'd had the same issue and found the (obscure) page that allowed you to undo the block. I assume they detected it simply by seeing DNS queries going to non-BT servers. Note this was a few years ago when it was pretty common for PC malware to hijack DNS requests, so could be it's changed in the meantime. N.B. I also recall BT redirecting requests for non-existent domains to some partner of theirs, I assume experimentally as I haven't seen or heard of that for a while.

    "N.B. I also recall BT redirecting requests for non-existent domains to some partner of theirs, I assume experimentally as I haven't seen or heard of that for a while" They are still doing this. I ran into it just yesterday. They do however make it very easy (click a couple of links) to turn it off.

      Still, interception of communications is a serious crime (unless your monopoly-scale ISP does it, of course). Thanks for the update (if somewhat depressing to know they still get away with it).
