I've been consulting (as a software developer) for a large home-building company for a while now and this experience has given me quite a few ideas and insight related to your #1. I'd be curious to hear you elaborate on this a bit more. Billions and billions of dollars go through this industry every year (even when it's down) and yet, the industry as a whole doesn't understand the web. So there are plenty of opportunities.

There is a lot of room in real estate -- from getting a mortgage --> finding houses on the multi-list.

I ended up getting my real estate license about a year ago just to not have to deal with agents (I have flipped a few houses). They were so inefficient it literally was painful.
