Since it is a static html file, not the result of a dynamic query to the 
DB, it's just a matter of adding a directive to any template:

<!-- TMPL_INCLUDE NAME="../../../cloud.html" -->

In my opinion, it works really well on the opac main page in a way that 
it is an enter point to the catalog as whole. You get an instant picture 
of catalog content and from that point you enter in the collection. I 
agree that it may not be the best solution for every library but nothing 
prevent controlling subjects cloud display on other pages with Syspref.

It could be very easily extended to generated other Zebra index clouds: 
Authors, Site, Libraries, Acquisition date, Specific subjects, etc. And 
when Zebra will be able to do index scan sorted by term weight, it even 
will be possible to do it dynamically!
