The admin fee adds to the problems, as unless they are going to force all existing users to pay it, and disconnect those that won't stand for it, then they will have to parallel run the two tariffs for quite some time, and I rather suspect that the 300k will also get the 5Gb cap, so staying with 1Gb/day@300k may not be an option.

I can see the reason for a lower cap, as otherwise the 750k users currently would have no reason NOT to downgrade to the cheapest tariff.

Anyway, I just put a monitor on for today - I think its OVER-estimating by counting the ARP traffic on the interface, and DHCP broadcast, but:
I set the alarm at 100Mb - about 3/5 of the daily total of 5Gb/month - allowing for 2Gb of additional downloads.

I estimate by the end of a total "non downloading" day, it'll be 60Mb - just 2/5 - looks like I'll be snatching 1Mbit / 5Gb cap, as I still have reasonable room for finding anything I want or need to download.

It helps if you KNOW what your current usage is, and then add some as faster generally means you'll use a bit more - some forums are 100k or more for each page, so 10 pages is a meg, and it soon adds up
