Using WebID and Linked Data to drive Data Space signup and login modality

All,

Here is another addition to my practical Linked Data and WebID 
exploitation re. the Read-Write aspect of the Web.

Scenario:

I have a personal data space on the Web, I want to control the following:

1. who can signup (register)
2. how they signup -- in this case, they must have a WebID (just one of 
many rules)
3. how they login -- in this case I've opted to allow members login 
using WebID or Digest Authentication (again, this is just one of many 
rules).

login modlity via WebID and Linked Data exploitation

associated with the same WebID and Linked Data exploitation theme re. 
Read-Write Web matters.
