So have most other people into mobile authentication also done.

Indeed, they make rather better use of client-authn certs than browser EVER did. I some sense, its like browsers were supposed to be (before PGP theorists threw out the baby with the bath water, for a quick fix [that didnt scale to a global trust model suiting consumers]).

Yes, browsers have essentially not improved since their inception w.r.t. X.509 client cert authentication.

If we do so, then one has a hybrid trust model world, that is not just an NSA/CIA/DHS/NIST/FISMA/openid cyberwar prep initiative. The same cert can also be used in webby interactions (for loosely coupled trust models). that the set of such interactions IS constrained by the MDM (which says one can ONLY talk to certain linked data endpoints) by governance policy does NOT worry me - since we are SEEKING a nuveau happyland, that mixes public/enterprise/cloud/personal models of crypto that are NOT founded in internet militarism.

The belief that "the same certificate" can be used in multiple and completely independent contexts is something that this group has got wrong which isn't very surprising since it is ignoring existing X.509 markets like on-line banks.  The same goes for the importance of Linked Data in other contexts than the social web.  Yes, IoT may be another venue but this field is owned by the "things"-vendors and they don't seem to hangout here.

Statements like "take full control of your online (Web and Internet) Identity" may sound cool but has essentially no value since just about all service providers have their own "identity system" which you either accept or reject.  The latter means you won't be able to use their services.  Calling this "take full control" is IMO quite a stretch.

Wouldn't it be better if this group realized that it is working on a particular problem and see how that can play together with other identity-using applications?  Then WebID could eventually even get a more useful authentication solution, something it will never be able to get on its own!
