I'd like to second 501261's thank you, JAFI.
Now as to the question: It is one or two pilots depending upon the equipment installed, working, and in use.
As I have said several times in this thread, one requirement is that the left seat pilot have and USE a boom microphone, in order to qualify for single pilot operations. No boom microphone for the left seat pilot, it's a two pilot aircraft and the SIC can log the time.
So get the PIC a headset without a mic, and you are in business. My interpretation, for what little it is worth (nothing!), is that if the left seat pilot unplugs his boom mic, that is probably sufficient.

Now back to the ISP, and this has always been an question for me, the Type Certificate, states one pilot, OR two pilots, which in my opinion separates it from other airplanes like the King Air, whose type certificate specifically states "one pilot".
Why "OR TWO PILOTS"?
I've felt that if you had a properly certified (61.55) SIC onboard and are operating as a crew, that SIC should be able to log the time as an SIC in a ISP or IISP because of the "Or two pilots" statement.
Of course the other school of thought is that if the SIC didn't show up and the flight is still legal to go, then that SIC shouldn't be able to log the SIC time.
I think the misperception is that a lot of people just throw a commercial pilot in the right seat and tell them they can log it all as SIC time. These "seat warmers" often do not meet the requirements of 61.55, and obviously should not be allowed to log any time.
On the other hand should a simulator trained SIC who flies every leg other be punished by not being able to log the flight time, because he's flying a 551 instead of a 550 (that could very well have been a 550 before it's "sex change", STC)?
