In home network, you share many types of files ! The first I think is DVD iso, 
which is huge (too large to go through coda) and not streamable... (but I 
admit it's not the best exemple !)

You share also documents (tax papers scans, ilness and doctors 
certificates...). And I share first of all Portage tree and distfiles !

Medias can be streamed, but not that !
