Registered sex offenders to provide Web ID.

There is a VERY good bill that is moving through the Kentucky Legislature. The bill (SB 65), which would make it a felony for a convicted sex offender -- Kentucky currently has over 61,000 registered sex offender -- to fail to register Internet user information, "is [intended] to protect children from online sexual predators" said Sen Ray Jones, a sponsor. To all you computer experts out there, how hard will it be to enforce the law, considering how "fluid and elusive" internet identification can be? Are there ways to have GREAT success and ENSURE STRICT enforcement of the URGENTLY needed law?
