Let me just give this one a bump here! I got tired of potential clients telling me that our competitors solutions offered mobile control where ours didn't. Nick's helped me come up with a solution using this "webserver" that we've successfully implemented and this stuff is great! We've basically created a web interface that serves up statuses, error messages, temperature and other I/O data, and even IP cameras all from the webserver to any mobile device or computer! If you have clients that are looking for mobile monitoring solutions say on an iPhone, Android, Blackberry, iPad, etc., this is definitely worth looking into.
This solution is lightweight and fairly simple to customize and Nick's been a brilliant help as well! Best of all I'm not having to pay large sums of money to an app programmer for a custom app for a particular device everytime... anyone with some basic HTML skills can pull this off.
