Well, I found the following three websites...

http://www.pem.com.au/
http://www.sdsefi.com/
I'm definitely not qualified to evaluate any of their claims. I sent an email to the first company - I'd expect it will take a while to hear back because of the time zone differences. I am curious mainly for environmental reasons - I've avoided carbs because of the emissions issues. A halfway decent alternative to CIS could make me very happy. I'll keep you posted if I get a reply.
