I think you can also look out for "next generation" FOAF profiles that
have a public key (WebID), have ACLs and allow a read/write Web eg.
through SPARQL Update, WebDAV, PushBack etc.

We're starting to see the very first of these emmerge, as
standardizations progresses in parallel.

This begins to close the loop in terms of a standard way to make a
semantic social collaborative space, with FOAF at the heart, and is
going to lead to hopefully a whole new wave of apps and innovation on
The Web.
