NHELD’s latest Bulletin about the Home School Non-Discrimination Act of 2005 [search ‘HoNDA’] is posted at North Carolina’s Homeschool Alliance Blog  And why should Illinois homeschoolers not like this bill?  Our exemption from the public school compulsory attendance statute is within our rights because we are identified as a private school with the same status as a brick and mortar private school.  We’re under their umbrella of protection, as well. 
Illinois homeschools=private schools.  Harvey Bluedorn wrote up a good piece about this issue of specifying "home school" in legislation when the problem was presented a few years ago by the same organization apparently on the lookout for new business.  From Bulletin Number 51:

Again, NHELD wants you to understand that by adding this type of language to federal law, we are opening the door to federal control of homeschooling. Whether the proposed legislation is helpful or not, State statutes will be superseded by federal law and you can lose many rights, even as some of these provisions seek to protect you. If the federal government mandates educational issues then these protections are appropriate, but the Tenth Amendment, and the intentions of the Founders were such that each state should have its own rules regarding educating its citizens. The implication of federal control of all means of education is something to consider, and we have seen how that has worked (or not worked) in the past, as well as in the present, in various countries around the globe. The question remains, do we wish to continue federalizing education and furthering legislation such as this? Or do we wish to fight for states rights and individual freedoms, especially as it relates to educating our children?
