Sorry, but for "get this some time in the future" for now don't see any 
use case at all. The interface I have in mind is like the spaces': 
get(id, obs) returns a block if we currently have it, otherwise null; if 
we don't have it we request it from the network, and if we can find it 
there, we fire the Obs so that the views will get refreshed. If no Obs 
is passed, we return null but don't issue a notification if new data 
arrives. Same with links: If we don't know if the network has additional 
links, we return those we have and spawn a lookup process, triggering 
the Obs once we've found any.
