"For quite some time it has been possible to access the Internet using mobile phones, although the role of the phone has strictly been that of a client. Considering that modern phones have processing power and memory on par with and even exceeding that of servers of the early web, there really is no reason anymore why webservers could not reside on mobile phones and why people could not create and maintain their own personal mobile websites."
I'm sorry, but this is just the silliest thing I've seen in a while. What happens when your data connection drops, or when your site starts to gain some popularity and you're phone can't handle the requests or the bandwidth? While I think it would be a neat idea, I don't think this is something that is worth doing. You're better off building an interface to control and update your website that is hosted someplace else. But that's just my $0.02, what do I know.
