I was looking at this the other day. Here's my findings:

1. Yes, sharing is easy. Turn on NAT and you're most of the way there.
2. Yes, you can track the WAN usage. I believe ipchains allows you to setup a filter that records the total data that goes through it. Setup one filter for your IP range, one for the WAN and you're done.
3. Yes, you can put limits on how much of your bandwidth you share, again through ipchains.

Now, the question is whether or not this is allowed by your ISP's terms of service. I can't get Cable at my house so I've only looked at Telecom, and the only paragraph I could find was:

'[You will] not run servers, use Static IP addresses or provide any public information service from a computer connected via this plan (or allow your account to be used for these purposes or in this manner);'

The words 'Static IP' are ambiguous, but apart from that it doesn't say you can't share it. And, as you pay for the data transferred, I can't see why they would want to stop you.

The big problem is what happens when you go over your data cap - who pays if you don't catch it in time?

I'm not sure really... In terms of the community that is starting based around the port hills antenna, I get the impression that it is simply a WLAN - ie access only to what people on the net want to share from their PC's harddrives - so there is no bandwidth that needs to be paid for really.
However, I don't see why somebody on the WLAN network couldn't expose their box as a gateway & allow their internet connection to be shared.
This brings up an interesting point - lets say I have joined this network & have some broadband connection I am willing to share, here are a few questions to the list:
- Can I share it? I'll assume yes, because my PC is just acting as a gateway/router.
- Can I track internet usage from the WLAN?
- Can I restrict the volume from the WLAN going through the net?
- Is there linux software that essentially allows me to act as an ISP?
- Is this legal (ISP terms & conditions I guess)

Anyhow, if I can get a connection to this WLAN from my place, I will be trying to do all of the above.
Comments/suggestions?

Cheers
Brad

How does the wireless net thing work? Do people just let others have free bandwidth? can anybody connect?
