Mark,

Yes, you can do nested loops.  Say you have a structure like this:

    {:title "Hello" 
     :slides 
     [{:caption "World"
       :images 
       [{:path "/img/world.png"}
        {:path "/img/space.png"}]}
      {:caption "Jupiter"
       :images
       [{:path "/img/callisto.png"}
        {:path "/img/ganymede.png"}]}]}

You can render this using the following template:

    {{title}}
    {{#slides}}
      {{caption}}
      {{#images}}
        <img src="{{path}}" />
      {{/images}}
    {{/slides}}

to produce this output:

    Hello
      World
        <img src="/img/world.png" />
        <img src="/img/space.png" />
      Jupiter
        <img src="/img/callisto.png" />
        <img src="/img/ganymede.png" />
    
There are even loop vars to reference the item and outer items from inside 
the loop:

    {{loop.item}}
    {{loop.outer.item}}
    {{loop.outer.outer.item}}

You can also bind each item in the loop if you don't like the implicit 
context:

    {{title}}
    {{#slides:slide}}
      {{slide.caption}}
      {{#slide.images:image}}
        <img src="{{image.path}}" />
      {{/images}}
    {{/slides}}

For the full list of loop variables available from inside a loop check out 
the template docs:  http://caribou.github.io/caribou/docs/templates.html
