Why?  If they're static sites, it would make sense to serve them as
static HTML.

You can re-use your static HTML documents as templates and serve them
through Catalyst, but afaics there's not much point unless you're going
to be making them dynamic.

You can definitely run multiple Catalyst applications (or multiple
copies of the same Catalyst application) on a single server using
fastcgi - I have 20 or so ShinyCMS installs on my server.  I haven't
tried the other methods.
