Obvious, but another example of why I think we need to look back and do some examination. Something built on a DHCP-like model (or, I suspect, on the sort of device identification model Claudio mentioned) probably means exposing the device and/or its location in all sorts of ways. That is precisely what assorted privacy efforts are trying to avoid. But Dave suggests (I think probably correctly) that one of the fatal flaws with ACAP is that it requires a username and hostname. That has other problems, but can also lead to a different set of privacy issues (including the potential for linking various credentials and device information). One can work around those issues using HTTPS with verifiable client certs, but that just changes the problem in other ways. Or one can move to a layered solution, hoping that opportunistic encryption based on traditionally largely-unverified server credentials will adequately hide the private stuff. Better be sure we know what problem we are trying to solve. john
