Oh yeah. I forget that faxed signatures are legally binding while otherwise electronically-sent signatures are not.

I'm not really sure how you can differentiate between faxed documents and scanned-and-emailed-and-printed documents. Or, for that matter, faxes that have gone through an email gateway. Or faxes that use the internet as a transmission medium instead of public phones lines. Or ones that are connected to VoIP lines on both ends, never having seen a POTS line, but using POTS technology at both ends.
