Canadian cable giant and ISP (Internet Service Provider), Rogers, is testing a system that enables it to inject messages to Rogers subscribers regarding their bandwidth usage. The company offers a tiered service with different bandwidth limits, the messages are meant to inform subscribers when they are nearing their limit. The move is setting off alarm bells with net neutrality advocates as the potential for using such technology for other purposes is very real. According to ArsTechnica, a Rogers spokesperson says "This is a trial to make it easier for our customers to keep track of usage. There is no deep package inspection and there is no privacy issue."
