Generally (Real Generally) the FAA likes to see one PIC . There are
exeptions to this of course, but someone serving as SIC shouldnt be
logging PIC.

I disagree. The safety pilot thing has already been mentioned. Instruction
of someone rated in the aircraft (maybe for a higher rating, maybe not) is
another. You are a CFII according to your post. When you were giving
instrument instruction, did you log it as PIC? Did your student?
That's a pretty common situation. If you meant really, really, really,
really generally, then ok.
