Draft F2F agenda entry on copyright and linking

Jeni,

I've made a first cut at the agenda entry for copyright & linking [1]. 
Please review and suggest changes as appropriate.

(please note that the rest of the F2F agenda is still under development and 
not yet ready for review)

Thank you.

Noah
