I like the idea of a browser level feature for opt in to WebRTC (on a per Origin basis) - and it was proposed circa 2011 web WebRTC was coming of age. It's probably worth revisiting that discussion.
Also with regards to detecting metering client side you're 100% correct - you can't reliably do it in any way on the client side (although for mobile there are some APIs to detect cellular vs. wifi [1]). What we do it we have a mapping of ASNs that are flagged as metered. When your client comes online we take the IP, map to the ASN and determine if it is able to upload. We buy this data today and you can always drop an email to [email protected] with your IP and we will add it in.
