Mustache templates?

[Eric B]

From what I can tell from the Mustache engine, Tiles is still rendering the mustache templates on the server side - correct?  If so, other than 
having another templating technology at your disposal (in addition to Velocity, Freemarker, etc), is there any additional advantage to using Mustache? 
 Isn't part of the attraction of mustache to render on client side?

Are there any examples how to use Mustache templates in Tiles? I looked around, but the only thing I could find was the Finn.no site 
(http://tech.finn.no/2012/05/15/putting-a-mustache-on-tiles-3/) which doesn't specify much.  ex: how to specify the different templates/partials/json 
objects to the mustache engine?  How does one export data to a mustache template?  I presume I can point the mustache engine to a url which generates 
a json object, or something of the sort?

Thanks,

Eric
