And maybe try to monetize it? I'm pretty sure that they can be compelled to do that, but do they do it for their own reasons too? Or is this way too much overhead to be doing en mass? (I vaguely recall that netflow, for example, can make routers unhappy if there is too much "flow").

Obviously this is likely to depend on local laws but since this is NANOG we can limit it to here.
