To me the underlying (and still unanswered) question is why you'd want
a "new SP" for each vhost? I take that to mean a seperate SAML SP with
its own entityID (and key pair, possibly)?

JFYI, for the shib-enabled (optional, via .htaccess files) mass
hosting environment we've built which hosted some several thousands
vhosts I believe (I've since changed positition and can't check for
details anymore) we opted for the exact opposit: Drive everything from
httpd config (which was generated programmatically) and never touch
the Shib SP config.
