That's the six million dollar question - what grade of service do you want
to provide to your users? Consider:

- Number of users signed up
- Number of concurrent connections
- Plans available - large or small Gb download per month
- Tail speed - 100Mbit vs. 1.5Mbit per user
- Local content availability
- Average b/sec per user per day

The upshot of these calculations will (usually) show something
between 1:25 to 1:100 for residential broadband users. So for as little as
66 end users, you may get away with a couple of Telstra DSL tails
multilinked together.
