It doesn't feel too onerous for CAs to implement. Having the keys bound to a single piece of hardware (or administrative sub-domain) is also what we had in mind.

It requires more coordination between servers (1 is > different; others need its IP; need some extra mechanism to > distribute key+cert once issued). We totally agree. The additional coordination overhead feels unnecessary and error prone. I am not at all familiar with the processes in an IETF WG. What is the way forward to get my proposal either into the protocol or officially dismissed? best regards, Jonas -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCgAGBQJWoMVYAAoJEMBiAyWXYliKmPwP/AhkeVsagYurFxAUdImIVDlB Dq8axBHes+WuZsYypmx7j1+zot4ljgZloxx6w//XfJyNyKdwNV1jrsFLBEELe3J9 kbcAYNZKO/DvN32GzluwF3yGqiovLCEsJ/DfRoIpcIzNSfCwutzR4h0vU9eZPjaR aAzUiyVF6rOz+eC1kIZuOvNRVXEOgSHWBiNiZMTsYSciiYls0jakGFmAN33O13Bi KJomFcQ8GWZJ261anTbLxgcGZYHFYjba4kZOShXX9VQnDkLrHC15aF0/afDZLjt5 ntSktX1JM+Qq1yN+FgJPPrk2B6JxvpS74um9DA8cwgMft+NU3hxpdwGaind3CVPp GqYcU0+Rm20mJOUYgJC3n/F6EnCeN75aQpZp82DLGoa5/oyCffgqJdcr4vcJfNk1 uI+8jmV13cgn0gzJUtWjHH09VUsaUfu6Da8QYhBKILYc+Lt2FgBNH/OVLiXyc/t9 eQKVdIMYZGxjsgE9oRGIG0qVXgloCB+N/5KSh/zUEt1WrqU2rJrtCF1wrk/zPvGa s2bh3DFCvf2GnPwDB3OrQzt3/1NpzLPKdccgvbAxUp1DAnrxeh3R1GHBji3k3dbj +8yPpaBaYstkB8rK9azCsvZ/D3jBIV5pv1LeMZ3oKCCmj2xDCk7kXonpKEAdruaR F2U+3WxFJbFMzpDocCIA =ftJz -----END PGP SIGNATURE-----
