I see, anyone with a $100 dollar modem can use any of these networks *right*
now for just the cost of the phone call. Right.

I've seen add's (maybe bogus, who knows) for $195 Fax Board plus software
for an IBM PC. Well ok that's more than $100. But certainly less than your
complete pc (generic) plus 1200 bps modem. With the introduction of the
Yamaha Fax Chip I think you'll see a dramatic drop for these types of boards
over the next two years. Up until recently Rockwell had a lock on the market
and didn't have any real competition to force them to bring the prices
down.


What you seem to be proposing here is YAEFSMS (Yet Another From Scratch EMail 
Standard).

What I'm suggesting is extending an existing successful standard. Specifically
transferring RFC-822 compatible messages using the proposed Fax FTP
standard.

You want people to figure out a new set of protocols for connecting,
establishing a common protocol, using a slow signalling technology, and
start from scratch. A suggestion - might be easier to start with Fido stuff
and work sideways.

I want people to utilize an existing set of protocols for connecting and
setting up the call, a faster signalling technology, and be able to hook
into a very large and successful user base; with the addition of some simple
mail transfer protocols to be used only when there is a computer at each end
of the connection (ie no *real* fax machines).
