Um, not really.
The IPC environment actually includes monitoring systems already, which you don't necessarily know about. In there are systems that distinguish bandwidth, so it knows what type of bandwidth is used to know where to send it. The caching system, RADIUS and DSL realms is also set up there, so that's where it stores data of which sites and IP ranges people use the most, so it can store it in cache. When a DNS query comes in, for example, it knows where to look for it, whether it's local or international and sends traffic on the correct path. You can also see in real-time what each user is doing. Many ISPs have different data packages, for instance, you could pay less for a Youtube package, where you pay less for Youtube traffic, but more for other Internet traffic and vice versa. For these systems to distinguish different traffic types, it has built in traffic monitoring and does not affect latency and usage since traffic has to pass through this IPC environment anyway to get routed.
I suggest you go take a look at some developments like Sandvine and also go read up a bit
here.
Traffic is already monitored by default, it's not like they're only implementing it now. They're only using it to their own advantage now by adding laws to what and what we're not entitled to do on the Internet.
