Huh?

WebID and SPARQL is about making an Endpoint with ACLs. ACL membership 
is driven by WebID for people, organizations, or groups (of either).

Don't really want to get into a Virtuoso vs 4-Store argument, but do 
explain to me how the convention you espouse enables me confine access 
to a SPARQL endpoint for:

A person identified by URI based Name (WebID) that a member of a 
foaf:Group (which also has its own WebID).

How does this approach leave ACL membership management to designated 
members of the foaf:Group?

Again, don't wanna do a 4-Store vs Virtuoso, but I really don't get your 
point re. WebID and the fidelity it brings to data access in general. 
Also note, SPARQL endpoints are but one type of data access address. 
WebID protects access to data accessible via Addresses by implicitly 
understanding the difference between a generic Name and a Name 
specifically used a Data Source Address or Location.
