Yes, if it was a mandate then elementary schools could use basic DNS servers to block then entire .xxx domain rather than having to try and use complex and expensive http content proxy filters that only partially work.
We used to evade the filter at school by entering IP addresses instead of normal URLs. (This also seems to work to evade the IWF.) Is there an easy way to block IP addresses based on a reverse-lookup match against .xxx?
Regardless, I could see this being used as an excuse to shunt porn sites to .xxx, even if doing so wouldn't actually solve anything.
