Well, the SIAIs strictly shouldn't be here, because they were built and flown (and ordered for series production).
For the Macchi bifusoliera and the Corsaro, refer here http://www.secretprojects.co.uk/forum/index.php/topic,2411.msg20201.html#msg20201, for the SM-91, here http://www.secretprojects.co.uk/forum/index.php/topic,2737.msg21883.html#msg21883 . Since I wrote that post, I have to make a correction (and update from my research): the final SM-91, ordered in March 1943 was to be a night-fighter and had special exhaust covers to mask the flames from the hot gases. The Sm-92 was to be the zerstorer.

Anybody know what the function of the torpedo like object on the tailplane was?

On the SM.92? Fairing for a remotely controlled MG mount.

So, more of a scare weapon rather than a serious attempt at a defensive one?  Aiming it by aiming the entire aircraft must have been interesting.

There was an article about tests with such (fixed) weapons in German aircraft in an Luftfahrt International
issue. It was said,  that aiming actually was quite easy, if a "Rückblickfernrohr" (rear view telescope/sight)
was installed.
It takes a long time, before all mistakes are made ...

I think with the aimer being offset in the port fuselage it would be quite difficult to "draw a bead" on an attacker, while it's location at the extreme rear of the aircraft would make the cone that it could fire in fairly limited, unless the aircraft was going to go into some pretty wild gyration.

As far as fixed tail-cone gun mounts went, the Do 217 was tried with similar arrangement,
 but it proved to be of not much utility, & was deleted.

Did the Italians get as far as 'handed' prop rotation as per P-38, P-82, D-H Hornet?

Was the Bf 109Z an independently or co-considered design - contemporary of the Italian jobs?

As far I know the Bf 109Z was something independent respect all Italian efforts (Caproni, Reggiane and Savoia Marchetti) to produce twin fuselage fighters.
For sure Italian designers were fascinated by P-38 while the various German "Zwilling" projects raised up as answer to some wartime operational issues.

Would second to archipeppe, the Me 109Z was an independent project to those from Italy, I think, although the reason behind
was the same: To get a fast win with better range and payload quick. The success with the He 111Z probably had triggered,
what actually became a kind of a tick, looking at the number of  twin-projects.
BTW, we had another italian twin here : http://www.secretprojects.co.uk/forum/index.php/topic,3465.msg61661.html#msg61661

Italian designer started to investigate the twin fuselage configuration long before the WWII, the very first project was the Bestetti-Nardi BN.1 started as research aircraft (technology demonstrator we would say today) rather than an operational machine.


The BN 1 was designed around 1937-39 and it made its maiden flight in July 1940.

There were quite a few twin-fuselage S.55 produced.  I think they somewhat predated all the German zwilling projects of WW2.  First, the aviation and aerospace community before WW2 was pretty small and fairly close-knit:  among other things, Mussolini's Italy funded a very large international conference and even paid the expenses for several aerodynamicists from the US.  Second, there was a lot of experimentation, with different configurations (tandem wing, twin fuselage, twin booms, flying wings, airfoil-shaped fuselages [Burnelli], etc) being tried.
