Some have suggested that a future network might require DSS signatures and make it illegal to send unsigned data. This would be a Bad Thing. I found this on comp.dcom.fax. It seems that a similar law is already in effect for fax machines. It is illegal to send a fax without an identification line on it! This is very similar to requiring a digital signature on a message, and sets a bad precedent. LO> The manual to my fax software quotes the following: LO> LO> FCC regulation part 68, Section 68.318 (c) (3) states that it is LO> illegal to send a fax in the U.S. which does not contain the LO> following sender information: LO> "...in a margin on the top or bottom of each transmitted page or LO> on the first page of the transmission, the date and time it is LO> sent and an identification of the business, other entity, or LO> individual sending the message and the telephone number of the LO> sending machine of such business, other entity or individual."
