So just looking at the iHug Broadband 3 fair use - http://www.ihug.co.nz/products/broadband/bband3_detail.html it really is just a 15GB plan. If you use over 500MB/day for 3 days straight then you get throttled to 64k. They are basically getting away with renaming the product without changing anything. In fact it is worse than the 15GB plan - Just think about downloading the latest Xcode Tools, a linux distro and all the patches for OSX over 3 days. You would be cut down to 64k even if you downloaded nothing for the rest of the month. At least on the old plan you would only be cut down after the whole 15GB was used.
IPTV, VOIP, etc. will never take off until we get these limitations changed. It is like having the bandwidth of a firehose and a bucket the size of a thimble.
