Capturing IMEI data and sending it to a remote server over a wifi network?

What would the cost be to make something like this? I envision it just being plugged into a wall communicating with a wifi network and sending data to a server. I'm guessing this is all feasible but for how much?

The one thing I havent seen is a way to pick up IMEI numbers and the strength of the devices signal. Maybe someone could point me in the right direction?

Thanks!

Obviously you have us confused with some geniuses who know what all these acronyms are :~

I think he confused us with people who respond to those who spam the forums with multi-posts.
