If you have such a setup your customers will lynch you since they're all
going to get awful performance.  That tends to be a self-correcting problem
-- you soon won't have any customers to worry about.

Yes, you're right.  You don't need a T1 to sell SLIP access.  

The fact is, however that you'll have so much congestion that packets will 
get tossed on the floor and performance will suck to the point that your 
users will think they're on 1200 baud modems.

There's actually one guy here in Chicago who was selling SLIP accounts to
people while he was on a 14.4kbps SLIP line to Alternet!  Now he's on a
56kbps line, and as far as I know his literature still claims to offer SLIP
to the public.

This despite the fact that (1) Alternet charges a serious fee to BGP peer 
with you, (2) without you doing that they have, in the past prohibited 
packet resale, and (3) anyone insane enough to BUY a SLIP account from 
this guy on these terms deserve(d) exactly what they got, and (4) he is, I
believe using a Netblazer for his backbone link! (can you say "no bgp"?)

I <REGULARLY> see 53-54kbps data rates on my 28.8 modem when I'm running
things like Mosaic and FTPs.  ONE of those calls and your 56kbps line is
buried.  Two and you start to have serious overcommitment problems.

I <design and build> nationwide networks for a living.  What you describe
just won't work well enough to keep ANYONE happy.
