DTI Pointers?

I'm taking public speaking so that I can finally get out of college and into the big wide world, and have decided to educate my class on the controversy surrounding the Digital Telephony Initiative. I need hardcopy to make my TA happy, and after an (admittedly quick) browsing of the archives, I wasn't able to find much in the way of hard information. Are there any good pointers, especially to the recent Lehman version of the bill and the controversy that now surrounds the EFF? Thanks in advance for your help, ozymandias G desiderata
