OK, alpha results of timing, show actually sending a query and receiving
a response takes ~500 - 800 ms. Total response time for a query 1.3~2.2s max,
if authentication required before query (but authentication request
can be sent by means of some cron sending OPTIONS & cookies every so often, 
to avoid session timeout; so counting that out, 500-800ms is what it takes 
for the server to answer the query).

Keeping in mind this is going to be running on FreePBX,
where do I start ;) if I wanted to marry this to CID Superfecta ?
Or should I rather look for how to write my own FreePBX module ?

You've mentioned 
'LWP::UserAgent and HTTP::Request and Text::vCard::Addressbook'
which I am going to research a bit.

The fun part would be to make the response from CardDAV into
an URL on which the operator shall click to bring the addressbook
details on screen 
(or just call firefox with url given as param that would do already ;) )
