Hello LD,
Although I can't help you re an answer yet, I wanted to register my interest in doing this too, and I'm sure it was possible, or at least possible for a short period a few years back, maybe as genealogy on the web was just taking off. I know that I surfed with a friend for a fee and we could search street names/addresses.
Does anyone know if this is still possible, and if so, where? I have a feeling that it was about 2004/5, and perhaps one of the censuses had just been put online?
Thanks all, Lav P
