So if ISP's are required to install monitoring software, what does that mean for HTTPS, or other end-to-end encryption schemes, that prevent the ISP from doing packet inspection?
This is just a guess but I don't think ISPs are expected to do any form of DPI. The most likely question they will have to answer is "who is this IP address assigned to?" and possibly "who communicated with that IP?". Neither require any form of packet inspection that goes beyond what is needed to perform routing.
