Many sites get away without having all their PC's in DNS, so apparently
very few web sites perform these kinds of checks.  I think the US
government lifted their restrictions on distribution of 128-bit
browsers,
so Microsoft and Netscape no longer try to use reverse DNS to check
whether
you're coming from the US (it was a very poor way to test, although as
good
as any other known technique).
