I dont' want to come off as a naysayer - I can see this taking off - but I do have some real questions. Maybe someone can enlighten me.

Don't you keep hard copies of these documents? Just wondering. For us, if it requires a signature, we usually need a hard copy (original) for our records.

Since we are printing it out (or receiving via fax in the first place), it seems just as easy to walk over to our $40 fax machine and send it (via our $9/mo Vonage fax line).

I am sure I am missing something here.
