It appears that TPM is being seriously considered by Copyright Policy Branch of Canadian Heritage, and has announced a paper by Dr. Ian Kerr and others. <http://www.pch.gc.ca/progs/ac-ca/progs/pda-cpb/pubs/protection/index_e.cfm>
It mentions a nice top heavy certificate rich method or a DMCA like law as two TPMs that might work in their opinion. The legal aspects are to be dealt with in a later part of the study, the tone is fairly optimistic that TPM can work well enough to preserve revenue to copyright controlers. I'm afraid I'll have to start writing letters to government and non-government groups to inform them of issues beyond revenue control issues (like creator's rights and consumer protection). -M Taylor --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
