Hi Jacopo,

We have included fingerprint lookup in our authentication module which
supports WebID+TLS.

The only issue here is that we are now talking about different protocol
i.e., not part of the WebID+TLS spec, as it currently stands. Thus, we
currently use the moniker NetID for this particular option.

Fingerprints are much easier with regards to manual setup of
WebID-Profile documents associated with WebIDs en route to PKI
exploitation in any authentication protocol.

Anyway, we take the same position as you i.e., its there as an option :)
