Who is "You" ?

The issue boils down to HTTP scheme URI and SAN entry.

Cost, to be clearer (on my part) also included fact that when something 
exists out in the wild the cost of production == $0.00 :-) Thus, I 
really meant: there are lots of certs like this already in the wild that 
don't use HTTP scheme URIs and nothing in SAN. This is really where 
Webfinger, Fingerpoint come into their own re. WebID vector potential.

But when you say that its akin to someone saying: although I talk about 
Semantics, I oriented towards Syntax for sake of simplicity. We can't 
keep on using "simple" in very subjective way.

As you know, I don't think WebID is about "Simply Simple" its is about 
"Deceptively Simple", that's inherited from its AWWW DNA courtesy of 
Linked Data.

> The advantage of SAN is that they are clearly defined for the purpose we are using them for, and you can put e-mail addresses in there too.

I understand that, but the real world already have Certs. constructed in 
the manner outlined. I really believe minimizing inertia is the key to 
boostrap. When I architect products at OpenLink I always oriented to 
"minimal inertia". To the uninitiated this appears to be a bizarre 
preoccupation with protocol implementation, but that's far from it. It 
about the pragmatics of real technology bootstrap by dealing with the 
realities out in the wild.

We don't need to tell people what's best for them if we can show them 
how a new technology makes what they already have better, with minimal 
(if any) inertia associated infrastructure changes etc..

Of course I am, the IdP is going to determine the canonical WebID and 
then de-reference it. You can de-reference a "mailto:" scheme URI using 
HTTP as exemplified by Webfinger and Fingerpoint.

If WebID can't alleviate the scourge of SPAM, what on earth is its 
ultimate purpose?

> SANs and IANs are scheme agnostic on the other hand.
So what? No the point when dealing with inertia reduction based on 
working with what exists already (however imperfect it might be).

You are making the same old mistake that most programmers have made 
repeatedly over time i.e., technology implementer (the coder, typically) 
knows best. Sadly, that isn't true. Users are typically domain and 
subject matter experts that are time challenged and don't write code. 
Being the one that writes the code != best comprehend-er of the 
discourse domain or the subject matter intrinsic to the domain.

>> and letting the IdP deal with the de-reference functionality. Remember, Linked Data is just a Webby way of handling de-reference and address-of operators that lies at the root of all forms of data access by reference.
