Let's put Comcast out of business.

Apparently the idea I had has already been done.

In December I moved from Texas to the Angle Lake neighborhood in Seatac, and I've been stuck with Comcast's shitty service for the last 9 months. Believe me, I was extremely surprised when I moved from tiny little Huntsville, TX and expected the seat of power for Amazon and Microsoft to have much better internet services... and the disappointment made me cringe. I've tried looking for other internet providers, but you have to go to their websites one-by-one and try to sign up, then when you enter your address they will tell you if they service your area or not.

So I had an idea, but I have no idea how to implement it, and would like ideas (or volunteers) on making this happen. I want to make a ISP overlay map for Google Maps. It would have the service zones mapped out for different providers, and you could simply enter your address into the search, and it would highlight which internet providers service that location.

So, does anyone think this is possible? And, what would you rate the difficulty level at?

And if you know what providers service Angle Lake, don't hold back. I'm suffering here. (Seriously, how does anyone put up with this terrible service?)
