John, I've left the entire text of my note and yours for reference.

No, that's about it.  It really is not an issue to have a legal, IFR, 
experimental class airplane.  Just make sure you go to the required 
equipment list and make sure you have everything on board.  Remember,  your 
VOR head must be checked and logged by you the pilot, pitot/static system 
checked, and if transponder equipped, transponder checked by a certified 
shop as per the regs.

There is a rather humorous requirement.  The regs say unless a moral pilot 
can safely clean the windscreen without adversely affecting the safe 
operation of the airplane, then a defroster is required.  How about the 
"immoral pilot".......guess it wouldn't apply to him:-)  No, I didn't find 
this, it was pointed out by someone else.

Once again, with that said, my own personnal opinion is the KR is not an 
acceptable IFR platform.  Others may feel differently on the issue.
