I can't think of a good solution. It's quite wasteful to use an entire resource for each entry, but that would let you use SiteAtoZ to present them and users could just create a new resource for any new entry and it would show up in the right place.
Using EZfaq, would be much more efficient and faster, but you'd have to create a jump list at the top and put anchors throughout (and "back to top" links). You'd only have to do that once, though. New entries would have to be added in place, but that's not all that difficult.
BTW, IIRC SiteAtoZ creates the jump list, the anchors, and the "back to top:" links dynamically, so you might be able to use that code to process the EZfaq content before showing it.
I haven't used FAQ manager, so I can't speak to that.
