Could xmlSocket be the solution?

Hi - we have a need at my office for an online tool which keeps track of the current status of about 20 people. Basically its function will be to orchestrate lunches/breaks and the availibility of lunches and breaks.

PHP/SQL would be the best solution, unfortunately I don’t have a legit server at my disposal. Best I can get is a half-*** file server.

Soooo does anyone here have experience w/ XMLsocket?
Can I dynamically update and review a shared XML document using this component?

I am hoping to hear the thoughts and feed back of someone w/ experience using this.

much thanks!
