CS:
As soon as you go on to multi-point injection, you're into an injector per cylinder and a complex and expensive box of electronics...or an equally complex and expensive mechanical injection-pump.
So I thought too, until Spunk pointed me to the description of the "Lycomming O360 FI System" (by Precision Airmotive)

Very interesting reading:
- single point metering controlled by diaphragms and what not
- mulit injector nozzel design, one per cylinder but in intake tube
=> absolutely no chance of icing (injector is very close to intake valve?)
=> absolutely no box of electronics
Hard to beat, regarding icing resiliance and simplicity of design, I'd say.
