I agree that it would be awesome if running servers at home would be commonplace. I think two main obstacles are (1) getting a static IP address, (2) ISPs terms

I agree that it would be awesome if running servers at home would be commonplace. I think two main obstacles are (1) getting a static IP address, (2) ISPs terms forbid business use. But for personal sites, I guess both can be overcome. I think I disagree that the router is the best way to do this. Keep components of the system simple and modular - a Pi type computer plus 'dumb' router seems like a better choice to me.
