Re: PDF accessibility guidelines. WAS: Re: PDF's and Signatures

but to the average person they put a document on a scanner (or scan it 
from a computer document) export it as a pdf and add it as an "attachment" 
in or after a document.  fast, simple, easy, but not very accessible.

got a full time IT dept yes it can be done but it is still not intuitive 
to the common user.  who more and more is not within the 
business/education community.

in a couple minutes I can take pretty much anything, scan it on a $100 
flatbed scanner, then send the result as an exported pdf document anywhere 
on the web.  or even worse send a scanned text document as a jpg. but we 
are not talking about that.
