I need to devise a system whereby all the people in my large office can use a web page (on our network somewhere) to let other people know where they are at any time, ie out to lunch, in a meeting etc.

I have 2 ideas...

1. Write 2 Exe's, one to run on a dedicated PC (always powered up) and the other as a user interface (instead of a webpage).

2. Write an ASP.net solution that would run the webpage.

Now, I know how to do (1) but I'm concerned about network traffic. I know (2) would be more efficient but I have no experience in ASP.net (and only a little in HTML page design).

Is ASP.net easy to learn? I am quite proficient at VB and a bit of C#.

Does anyone have any advice about what I should do? My deadline is 2 weeks or so to ave the beta version up and running.
