...and this is the tricky part---you want tightly defined functionality, and other people want to install a photo-sharing that just works with their off-the-shelf smart TV. In principle, both could be accomplished with a combination of well-written, good-looking pop-up dialogs and a smart, dynamic firewall, but the required software doesn't exit yet.

I think that we should start with the low hanging fruit and simplify the firewall zones to two : a public, restricted one and a home/private with more ports open; selected by user for each new interface.
