Well by US law, all new web sites for US corporations should be accessable.. many still aren't, and the government has been slow to enforce the law, but we've been tasked to make ours easy, and more accessable...

the US Government is the largest retailer on the Web! you can by US postage stamps, permits, publications, salvage goods, land, excesses and goodness knows what else... and all of the pages are designed to be accessable!
