What RFCs say (or don't say) about 240/4 means precisely nothing to the deployed, non-field-upgradable CPE that I understand is driving the interest draft-weil. That IMO is the rock that proposals to use Class E have floundered on. There is a lot of gear out there that will not be able to deal with any Class E internetworking protocol, little prospect that that will be changed any time soon, and a general feeling that it is unwise to spend limited resources changing this.
