OpenHomez Web Site Lists Open Houses For The Public

I came across an interesting web site, openhomez.com which lists various open houses for the general public. I am not sure about it's market penetration to date, but I would imagine that it would continue to expand it's reach moving forward. Anyway, just an idea for those who would like to preview Dallas open houses online - before driving the streets looking for open houses in Dallas and the surrounding DFW metro-plex.
